Ok so what you're trying to do is get L by itself so to do this you move everything to the other side:
A=L*WH
![\frac{A}{WH}](https://tex.z-dn.net/?f=%20%5Cfrac%7BA%7D%7BWH%7D%20)
=L
So you answer would be:
C
Answer:
Step-by-step explanation:
<u>Solving in steps</u>
- 3| 4.5 - 2| - 5 |-1.5 -(- 3)| =
- 3 |2.5| -5 |-1.5 + 3| =
- 3*2.5 - 5|1.5| =
- 7.5 - 5*1.5 =
- 7.5 - 7.5=
- 0
Answer:
![y=9](https://tex.z-dn.net/?f=y%3D9)
Step-by-step explanation:
First, let's find the value of x.
Note that the two equations with the x are alternate interior angles. Therefore, their angle measures are equivalent. So, we can write the following equation:
![5x-38=3x-4](https://tex.z-dn.net/?f=5x-38%3D3x-4)
Solve for x. Let's add 38 to both sides:
![5x=3x+34](https://tex.z-dn.net/?f=5x%3D3x%2B34)
Subtract 3x from both sides:
![2x=34](https://tex.z-dn.net/?f=2x%3D34)
Divide both sides by 2. So, the value of x is:
![x=17](https://tex.z-dn.net/?f=x%3D17)
We can see that we have a right triangle.
The sum of the three interior angles of a triangle is always 180. Therefore, we can write that:
![90+(7y-20)+(5x-38)=90](https://tex.z-dn.net/?f=90%2B%287y-20%29%2B%285x-38%29%3D90)
Since we already know that x is 17, substitute 17 for x. This yields:
![90+(7y-20)+(5(17)-38)=180](https://tex.z-dn.net/?f=90%2B%287y-20%29%2B%285%2817%29-38%29%3D180)
Now, we can solve for y. Multiply:
![90+(7y-20)+(85-38)=180](https://tex.z-dn.net/?f=90%2B%287y-20%29%2B%2885-38%29%3D180)
Combine like terms:
![(7y)+(90-20+85-38)=180](https://tex.z-dn.net/?f=%287y%29%2B%2890-20%2B85-38%29%3D180)
Evaluate:
![7y+117=180](https://tex.z-dn.net/?f=7y%2B117%3D180)
Subtract 117 from both sides:
![7y=63](https://tex.z-dn.net/?f=7y%3D63)
Divide both sides by 7. So, the value of y is:
![y=9](https://tex.z-dn.net/?f=y%3D9)
And we're done!
The problem would equal 8
