Hello there, this problem is just basic addition, here is what it would look like

Solve it and we get 78.21
(10x+5)4 = 30x + 3x + 6x +30
40x + 20 = 39x + 30
X = 10
perimeter of the square= 420
perimeter of the triangle= 420
The answer should be A. 4.5
Because line x is just over half of the length of the line that is 8ft
Answer:
b
Step-by-step explanation:
Volume of A= πR².H ==> V(A)=4π m³
Volume of V =πR².H ==>V(B)=8π m³
.Ratio of A to B =(4π) /(4π) = 1/2
