Answer:

Step-by-step explanation:

2x+2=10 subtract 2 from each side

2x=8 divide each side by 2

x=4 is the correct solution.

Her error was most likely subtracting 2 from the left and adding 2 to the right

2x+2=10

2x=12

x=6

The length of a rectangle is three more than twice the width. The perimeter is 96. What are the dimensions? ​
SIZIF [17.4K]

Answer:

Width =15

Length =33

Step-by-step explanation:

Take width as x

And length as 2x+3

Perimeter as 96

Formula of the perimeter of a rectangle is 2l+2w

X+×+2×+3+2×+3=96

6x+6=96

6x=96-6

6×=90

X=15

Width =x and x =15 so width =15 while length =33
