Answer:
[tex]\frac{1}{3(x-2)}[/tex]
Step-by-step explanation:
Hi there!
We need to multiply the fractions:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{x^{2}+x-6}[/tex]
Before we multiply, we can cancel out and factor the polynomials to make multiplying easier
First, we can factor x²+x-6
1 (in front of +x) is the sum of two numbers and -6 is the product of those numbers
Those numbers are -2 and 3
so when we factor, we get:
(x-2)(x+3)
here are the fractions so far:
[tex]\frac{x+3}{12x}[/tex]×[tex]\frac{4x}{(x+3)(x-2)}[/tex]
we can cancel out x+3 on both fractions
[tex]\frac{1}{12x}[/tex]×[tex]\frac{4x}{x-2}[/tex]
we can also cancel out 4x from both fractions
[tex]\frac{1}{3}[/tex]×[tex]\frac{1}{x-2}[/tex]
now multiply the fractions together
[tex]\frac{1}{3(x-2)}[/tex]
So the first option is your answer
Hope this helps! :)

Answer:
d = 67.5
e = 22.5
Step-by-step explanation:
d + e = 90
d = 3e
Therefore, we can simply divide 90 by 4, which gives us 22.5, and also tells us what e equals. Then, multiply that by 3 to get d.

Answer:
x=10
Step-by-step explanation:
To solve for x, you need to draw an imaginary line connecting the right end of side x to the left side with length 15. This forms a triangle with side lengths 6 and 8, and hypotenuse x. Using the Pythagorean Theorem to solve for x, we get 6^2 + 8^2 = x^2, 36 + 64 = 100, [tex]\sqrt{100}[/tex] = 10.
Answer:
It's 10
Step-by-step explanation:
C^2=A^2+B^2blank
C=√(A^2+B^2)
If c is x and a and b are the side lengths the we can use Pythagoras's theorem to calculate the length of the line. A=6 B=8 and in the end when you calculate all that doohickey stuff you get x=10
Divide: 5 + 2i by 3 + 4i.
Answer:
1-2i
Step-by-step explanation:
Divide: 5 + 2i by 3 + 4i.
Given data
5 + 2i by 3 + 4i.
We have the expression as
(5 + 2i)/(3 + 4i)
Rationalize the denominator
(5 + 2i)/(3 + 4i)* (3 -4i)/(3 -4i)
=(5*3-20i+6i-8i^2)/9-12i-12i+16i^2
=15-14i+8/9-16
=7-14i/-7
=1-2i
SOMEONE HELP, I HAVENT BEEN PAYING ATTENTION TO CLASS
Answer:
A=4cm
ok to do this we do the formula
A=PiR^2
A=3.14*4^2
A=3.14*16
A=50.24
and the area of circle B is 4 times the area of a so
50.24*4=200.96
200.96=3.14*X^2
Since r is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96 Divide each term by 3.14 and simplify.
r 2 = 64
r=8
CIRLCE A=50.24
CIRLCE B=8

Contruction workers are building a brick wall. The wall needs to be 3 feet tall, and the builders have enough bricks for the wall to have a volume of 279 cubic feet.What will the area of the base of the wall be?
Answer:
[tex]Base\ Area = 93ft^2[/tex]
Step-by-step explanation:
Given
[tex]Volume = 279ft^3[/tex]
[tex]Height =3ft[/tex]
Required
The base area
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
This gives:
[tex]279= Base\ Area * 3[/tex]
Make Base Area the subject
[tex]Base\ Area = \frac{279}{3}[/tex]
[tex]Base\ Area = 93ft^2[/tex]
Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Answer:
A. It increased both her intensity and her workout time.
Step-by-step explanation:
A. It increased both her intensity and her workout time.
B. It decreased her intensity but increased her workout time.
C. It increased her intensity but decreased her workout time.
D. It decreased both her intensity and work out time
Last week = 4 miles per day
This week = 5 miles per day
Intensity refers to how hard one exercises.
Workout time refers to how long one exercises the body.
By adding a mile, she has increased how hard she exercises her body (intensity))
And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

Solve the following equations:
a)
4b = 20
Answer:
b = 5
Step-by-step explanation:
You want to get b on one side alone so you divide by 4.
20 divided by 4 is 5.
Answer:
b = 5
Step-by-step explanation:
4b = 20
Whatever we do to one side of the equation, we have to do to the other.
To "isolate the variable", or get "b" by itself, we have to divide both sides by 4
4b divided by 4 is b, since "4b = 4 times b"
20 divided by 4 is 5
4b = 20
b = 5

The graph of the linear equation can be seen below.
Which graph represents the given function?
Here we have the linear function:
y = 5x + 3
To graph this, we need to find two points on the equation and then connect them with a line.
By evaluating in 0 we get:
y = 5*0 + 3 = 3
So the point (0, 3) is on the line.
By evaluating on 1 we get:
y = 5*1 + 3 = 8
So we have the point (1, 8).
Now we just plot them and connect them with a line, the graph is the one below.

Can someone help I don’t understand my answer are not adding up
Answer:
B
Step-by-step explanation:
∠ ABC = 9x + 5 ( alternate angles )
∠ ABC and ∠ DCB are sam- side interior angles and sum to 180° , that is
9x + 5 + 16x = 180
25x + 5 = 180 ( subtract 5 from both sides )
25x = 175 ( divide both sides by 25 )
x = 7
Then
∠ ABC = 9x + 5 = 9(7) + 5 = 63 + 5 = 68° → B
