Find the distance between each pair points
Lisa is building a garden in her backyard in the shape of a right triangle and wants to put a fence around it to keep her dog out.
The longest side of the garden is 20 ft and one of the shorter sides is 9 ft. How long does the 3rd piece of the fence have to be?
Round this value however you need to. The exact length is sqrt(319)
In other words, sqrt(319) = 17.8606
=======================================================
Work Shown:
a = 9 is one of the legsb = unknown is the other legc = 20 is the hypotenuse, aka longest sideApply the pythagorean theorem to solve for b.
a^2+b^2 = c^2
9^2 + b^2 = 20^2
81 + b^2 = 400
b^2 = 400-81
b^2 = 319
b = sqrt(319)
b = 17.8606 which is approximate
I'm going with the approximate value it makes more sense to do so in this case. Saying "the length is sqrt(319)" to someone not familiar with math, would probably not convey just how long the third side must be. Round the value in bold however you need to.
Solve for P.
-1 + 14 p = -435
Answer:
P = -31
Step-by-step explanation:
-1 + 14p = -435
Remove the -1 by adding it from both sides.
14p = -434
Remove the 14 by dividing it from both sides.
p = -434/14
p = -31
Answer:
-31
Step-by-step explanation:
-1+14p=-435
14p=-435-(-1)
14p=-435+1
14p=-434
p=-434/14
p=-31

In the map below, the path from the zebras to the monkeys is parallel to the path from the tigers to the elephants.
A map of the City Zoo. A triangle has points Zebras, Monkeys, lions. The distance between zebras and monkeys is 80 feet and from monkeys to lions is x feet. A triangle has points tigers, elephants, lions. The distance from lions to tigers is 132 feet and from tigers to elephants is 120 feet.
What is the distance between the lions and the monkeys?
40 feet
88 feet
92 feet
198 feet
Answer:
64ft
Step-by-step explanation:
The distance between the lions and the monkeys is; 64 ft
How to calculate distance using similar Triangles?From the given diagram, we see two triangles;
Triangle one formed by Zebras, Monkeys, lions.
Triangle two formed by tigers, elephants, lions
Now, from the given triangles we can see that they are similar and using the given dimensions, we can use proportion to find distance between the lions and the monkeys as;
52/78 = x/96
where x is the unknown distance we are looking for
We cross multiply to get;
4992 = 78x
Divide both sides by 78 to get;
x = 64 ft

Felipe’s solution to an equation is shown below:
Given: x^2+6x+8=0
Step 1: (x+2)(x+4)=0
Step 2: x+2=0 or x+4=0
Step 3: x= -2 or x= -4
Which property of real numbers did Felipe’s use for step 2?
A. Distributive property of multiplication over addition
B: Multiplication property of equality
C. Commutative property of multiplication
D: Zero product of multiplication
Answer:
D. Zero product of multiplication
Step-by-step explanation:
The given equation is presented as follows;
Given: x² + 6·x + 8 = 0
By factorization, to find numbers represented by variables, 'a' and 'b', such that a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation
Step 1: (x + 2)·(x + 4) = 0
Given that (x + 2) × (x + 4) = 0, we have
Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication
The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero
Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0
By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0
Therefore, we have;
Therefore;
Step 3: x = -2 or x = -4
The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.
HELP/ solve for x. Write your answer as "x=__"
Answer:
Hello! answer: x = 50
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees! so...

Answer:
a) There are 4 terms.
b) 2 of them are negative
explanation:
Let's simplify step-by-step.
−3x^2+2y^2+5xy−2y+5x^2−3y^2
=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2
Combine Like Terms:
=−3x^2+2y^2+5xy+−2y+5x^2+−3y^2
=(−3x2+5x^2)+(5xy)+(2y^2+−3y^2)+(−2y)
=2x^2+5xy+−y^2+−2y
Answer:
=2x^2+5xy−y^2−2y
Answer:
Step-by-step explanation:
A. There are 6 terms. Even if there is a variable onto the coefficient, it wouldn't be 2 terms but only 1, in this case, there are 6 terms.
B. If I simplify the number of negative terms, there would be 2 terms.-3x^2,-2y, and -3y^2 are all negative terms in this equation. I can't combine all because one has x as a variable and the other 2 has y. If I simplify both of the negative terms (-2, -3y^2) Ill get -5y^2. -2-3= -5 and just add my other values y and 2 square, and in that case, my final 2 negative terms are -3x^2 and -5y^2

someone please do a step by step for this linear equation
Help urgent
I need this done quick
Answer:
It is supplementary.
Step-by-step explanation:
Supplementary angles are angles that have two angles adding up to 180°. You can tell by just finding the straight line that equals 180° then seeing a line that separates the whole measurement into two angles, but together making a 180° angle still. Hope this helps! :D
Meanings of the other Options:
Alternate Interior Angles - Angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal.
Corresponding Angles - Angles that are in the same relative position at an intersection of a transversal and at least two lines. If the two lines are parallel, then the corresponding angles are congruent.
Alternate Exterior Angles - Angles are the pair of angles that lie on the outer side of the two parallel lines but on either side of the transversal line. Exterior angles lie on opposite sides of the transversal but outside the two parallel lines.
Parallel Lines - Two lines that never intersect. Like an equal sign for example (=).
Transversal - A line the cuts through a parallel line. Like a non-equal sign for example (≠).

The radius of a sphere is 12 units. Find the volume of the sphere. Write your answer in terms of pi.
Answer:
V = 2304π units³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( where r is the radius ) , then
V = [tex]\frac{4}{3}[/tex]π × 12³
= [tex]\frac{4}{3}[/tex] π × 1728
= 4π × 576
= 2304π units³
In a specific arithmetic sequence, if -4 is the first term and 10 is the third term, which term is 157?
Step-by-step explanation:
everything can be found in the picture
The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180
Arithmetic sequenceThe nth term of an arithmetic sequence is expressed as:
Tn = a +(n - 1)d
where
a is the first termd is the common differencen is the number of termsIf -4 is the first term and 10 is the third term, then;
a = -4
a + d = 10
d = 10 - (-4)
d = 14
Determine the 157th term
T157 = -4 + (157 - 1)(14)
T157 = -4 + (156*14)
T157 = 2180
Hence the 157th term of the sequence is 2180

how do i find the area for number 4?
Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
The bottom rectangle has area of 4*8 = 32 cm^2The top rectangle has area of 3*3 = 9 cm^2The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:
Area = Length x Width
A = L x W
To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them
