Answer:
The correct answer is Option D. 20
Step-by-step explanation:
From the figure we get,
<RUS = 90° because RU ⊥ TS
<u>To find the value of x</u>
It is given that <RUS = 4x + 54
Therefore we can write,
4x + 54 = 90
4x = 90 - 54 = 36
x = 36/4 = 9
<u>To find RS</u>
It is given that,
RS = 3x - 7 = 3*9 -7 = 20
Therefore the correct option is Option D . 20
Step-by-step explanation:
directrix = (1, -1)
focus = (-3, 2)
vertex = (-3, 3)
Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:
![\frac{1}{2} (x+18) = 4(2x-6)-9x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%28x%2B18%29%20%3D%204%282x-6%29-9x)
I simplified the problem to:
![\frac{1}{2} x+9 = 8x-24-9x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%2B9%20%3D%208x-24-9x)
I combined like terms:
![\frac{1}{2} x+9 = -x-24](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%2B9%20%3D%20-x-24)
I moved all x to one side and all other constants to the other:
![\frac{3}{2} x = -33](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20x%20%3D%20-33)
I divided by 3/2 (1.5) on both sides to isolate x:
![x = 22](https://tex.z-dn.net/?f=x%20%3D%2022)
Hope it helps! (:
Answer:
3/40
Step-by-step explanation:
area of a triangle is 1/2 x base x height
base = 19
height = 3
19 *3 = 57
1/2 x 57 = 28.5 square ft.
