Two numbers multiply to be 4 and add to be -5

Round this value however you need to. The exact length is sqrt(319)

In other words, sqrt(319) = 17.8606

=======================================================

Work Shown:

Apply 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.

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

Answer:

64ft

Step-by-step explanation:

The distance between the lions and the monkeys is; 64 ft

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

Answer:

Hello! answer: x = 50

Step-by-step explanation:

This is a supplementary angle meaning it will add up to 180 degrees! so...

50 × 3 = 150 150 - 20 = 130

130 + 50 = 190 therefore x = 50 hope that helps!

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

I have no idea but maybe if you would pay attention in class you would know how to do it. I just need my points so I can keep getting answers. good luck tho

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 (≠).

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

The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180

The nth term of an arithmetic sequence is expressed as:

Tn = a +(n - 1)d

where

If -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
