Answer:

x = 1/4

Step-by-step explanation:

Expand the square, then solve the resulting 3-step equation.

81x +1 = 93x -2

1 = 12x -2 . . . . . . . . . subtract 81x

3 = 12x . . . . . . . . . . . add 2

3/12 = 1/4 = x . . . . . . divide by 12 and reduce the fraction

The solution is x = 1/4.

The length of a rectangle is 2 feet longer than its width the perimeter is 16 feet. find the dimensions of the rectangle.

sergiy2304 [10]

So you would have to set up a equation to find the length and width. The equation would be w+(w+2)=16

that simplifies to 2w+2=16

2w=14

w=7

the width is 7

the length is 9
