No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7
$755 each this is so simple you just divide 2265 by 3.

Answer:
answer is D
Step-by-step explanation:
2^4=16
16+(16-12)=20
over
(6+9)/(7-4)
15/3=5
so the new equation is 20/5=4
