The rectangle below has an area of 49-x^2 square meters and a width of 7+x. what expression represents the length of the rectangle?

( 7-x ) meter.

Step-by-step explanation:

Rectangle has an area of and width of the rectangle is given as ( 7 + x).

We have to find expression that represents length of the rectangle.

Since area of rectangle = Length × width

× length

× length

[Since

Length =

= (7-x) meter

idk lol

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
