The length of a rectangle is represented by the function l(x) = 2x. the width of that same rectangle is represented by the function w(x) = 8x2 − 4x + 1. which of the following shows the area of the rectangle in terms of x?

(l + w)(x) = 8x2 − 2x + 1
(l + w)(x) = 8x2 − 6x + 1
(l ⋅ w)(x) = 16x3 − 4x + 1
(l ⋅ w)(x) = 16x3 − 8x2 + 2x

Area = LW

Area = 2x (8x^2 − 4x + 1)

Area = 16x^3 - 8x^2 + 2x

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
