11. The rectangle has a width of 8 in, a length of x-5 in, and an area of 16 in). Solve for x. Hint: label the figure.
x-sin
sin

Use the area of rectangle formula which is:

Given that:

Substitute in the formula:

Distribute 8 in the expression:

Move -40 to another side and change from -40 to 40.

Then move 8 to divide 56, leaving only x.

Hence, the answer is:

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
