Answer:
B
Step-by-step explanation:
So therfor from 19-6x to 2+4x the diffence if the same as the diffence between 2+4x an d6x+1
so (2+4x)-(19-6x)=(6x+1)-(2+4x)
add like terms
2+4x-19+6x=6x+1-2-4x
10x-17=2x-1
add 17 to both sdies
10x-2x+16
subtract 2x form both sdies
8x=16
divide boht sdie syb 8
x=2
x=2
therfor the terms are
7, 10, 13
Alrighty-
So here we go.
Let's first go over any given values.
Shortest side = s
And we know that
3rd side = 12
Now for the longest side
"Three more" means +3
"...twice as long as the shortest side"
Means 2s
Longest side = 3+2s
Now we put this in the correct format:
P = 12 + s + (3+2s)
We can simplify further:
P = 12 + s + 3 + 2s
P = 15 + s + 2s
P = 15 + 3s
ANSWER: P = 12 + s + (3+2s)
SIMPLIFIED: P = 15 + 3s
