                                    2x³ + 17x² + 46x + 40 = l(x + 4)(x + 2)
                 2x³ + 12x² + 16x + 5x² + 30x + 40 = l(x + 4)(x + 2)
2x(x²) + 2x(6x) + 2x(8) + 5(x²) + 5(6x) + 5(8) = l(x + 4)(x + 2)
                     2x(x² + 6x + 8) + 5(x² + 6x + 8) = l(x + 4)(x + 2)

Answer:

2x + 5 = l

Step-by-step explanation:

V = lwh

                                  2x^3 + 17x^2 + 46x + 40 = l(x + 4)(x + 2)

            2x^3 + 12x^2 + 16x + 5x^2 + 30x + 40 = l(x + 4)(x + 2)

2x(x^2) + 2x(6x) + 2x(8) + 5(x^2) + 5(6x) + 5(8) = l(x + 4)(x + 2)

                    2x(x^2 + 6x + 8) + 5(x^2 + 6x + 8) = l(x + 4)(x + 2)

                                        (2x + 5)(x^2 + 6x + 8) = l(x + 4)(x + 2)

                                 (2x + 5)(x^2 + 2x + 4x + 8) = l(x + 4)(x + 2)

                        (2x + 5)(x)(x) + x(2) + 4(x) + 4(2)) = l(x + 4)(x + 2)

                                 (2x + 5)(x(x + 2) + 4(x + 2)) = l(x + 4)(x + 2)

                                     (2x + 5)(x + 4) + 4(x + 2) = l(x + 4)(x + 2)

                                               (x + 4)(x + 2)               (x + 4)(x + 2)

                                                                     2x + 5 = l

Help me I need help I need help
Licemer1 [7]

Answer:

\Huge\boxed{131.88}

Step-by-step explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88

So we can conclude that the circumference of the circle is 131.88 inches
