The lenghtvof each side of a square is 2.5 meter. if each side is doubled in length, what is the effect on the perimeter of the square? a. it remain the same b. it is one half the original perimeter c. it is four time the original perimeter d. it is twice the original perimeter.

T=4.5

Simplifying 3t + 4 = t + 13
Reorder the terms: 4 + 3t = t + 13
Reorder the terms: 4 + 3t = 13 + t
Solving 4 + 3t = 13 + t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-1t' to each side of the equation. 4 + 3t + -1t = 13 + t + -1t
Combine like terms: 3t + -1t = 2t 4 + 2t = 13 + t + -1t
Combine like terms: t + -1t = 0 4 + 2t = 13 + 0 4 + 2t = 13
Add '-4' to each side of the equation. 4 + -4 + 2t = 13 + -4
Combine like terms: 4 + -4 = 0 0 + 2t = 13 + -4 2t = 13 + -4
Combine like terms: 13 + -4 = 9 2t = 9
Divide each side by '2'. t = 4.5
Simplifying t = 4.5
