Sagot :
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

Answer:
Step-by-step explanation:
Alright, lets get started.
The side length of square is given as 2.5.
So, the perimeter if square will be : [tex]4*2.5=10.0[/tex]
Once the side is doubled, means new dimension of side of square will be : [tex]2*2.5=5[/tex]
So the new perimeter will be : [tex]4*5=20[/tex]
The original perimeter is 10.
The new perimeter is 20.
It means the perimeter is twice the original perimeter. : Answer D
Hope it will help :)
