8-/x(x-4)/x-3
That should be it if you can’t understand it the whole equation after the eight is a fraction
Answer:
-51
Step-by-step explanation:
5x + 3y -7z = 5 x 4 + 3 x -5 - 7 x 8
= 20 - 15 - 56
= -51
Answer:
15 ft
Step-by-step explanation:
Let the height of the wall be represented bad x
Applying the theorem of similarity, we would have the following equation:



Cross multiply

2x = 30
Divide both sides by 2
x = 15
Thus, the height of the wall = 15 ft
