1) find the value of x.
(5x + 15)
(6x - 10)

x = 25

Step-by-step explanation:

We know that they are the same on both side

5x + 15 = 6x - 10

+ 10 to both sides

5x + 25 = 6x

Subtract 5x from both sides

25 = x

Let's check it:

5(25) + 15 = 140

6(25) - 10 = 140

This is reasonable, since we know it has to be more than 90 but less than 180.

answer: options?

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
