Step-by-step explanation:

Ben is planning to fence his rectangular garden. The area of the garden is 50 square feet, and the length of the garden is twice the width.

LEt x be the width of the fence

the length of the fence is twice the width.

Length of the garden = 2 * width = 2x

ARea of the garden = length * width

Plug in 2x for length and x for width

Area is 50

Divide by 2 on both sides

Take square root on both sides

x= 5

So width of the fence = 5 feet

Length of the fence = 2x= 2*5= 10 feet

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
