X=7
after you remove parentheses you do those steps
3/8=x/20
Multiply both sides by 20.
20(3/8) = 60/8 = 15/2 = 7.5
7.5 = x

Answer:
64 : 729
Step-by-step explanation:
Ratio of surface area
= (ratio of linear dimensions) ^2
= 1.6^2 : 5.4^2
= 256 : 2916
= 64 : 729
√(t + 3) = 14 ← -2 both sides
t + 3 = 196 ← square both sides
t = 193 ← subtract 3 from both sides
5x² + 8x + 3 = 0 ← put in standard form
(5x + 3)(x + 1) = 0 ← factor
5x + 3 = 0 or x + 1 = 0 ←Zero product property
x =
or x = -1
