Find x and the perimeter of the triangle.

x=
perimeter=

x=10

perimeter=129

step wise

4x+7=5x-3

4x-5x=-7-3

-1x=-10

x=10

then,

perimeter=(4×10+7)+(5×10-3)+(4×10-5)

=129 answer

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
