Isolate the h. Do the opposite of the sign given - Because of equal sign, what you do to one side you do to the other
h/4 = 9
h/4(4) = 9(4)
h = 9(4)
h = 36
36 is your answer for "h"
hope this helps
Since the triangles are similar, we can use ratios to find what x equals.
Ratios:
3x+8/4 = 25/5
The easiest way to solve ratios, in my opinion is to cross multiply.
3x+8*5 = 4*25. Simplify to get 15x + 40 = 100.
Subtract 40 on both sides. 15x = 60.
Divide 15 on both sides. x = 4.
The answer is 20x hope this helped :)
