Answer:

-8

Step-by-step explanation:

if you sub in 8 as the value for y, you get

-4x - 8 = 24

add 8 on both sides to simplify

-4x = 32

divide both sides by -4

x = -8

The area of a rectangle is (x3 – 5x2 + 3x – 15), and the width of the rectangle is (x2 + 3). If area = length × width, what is t

lisabon 2012 [21]

Answer:

D

Step-by-step explanation:

The area of a rectangle is given by the formula:

$A=lw$

So, we are given that the area is:

$x^3-5x^2+3x-15$

And the width is:

$x^2+3$

And we want to find the length. To do so, first substitute the expressions into the equation:

$x^3-5x^2+3x-15=(x^2+3)l$

Thus, to find the length, divide by (x²+3):

$l=\frac{x^3-5x^2+3x-15}{x^2+3}$

So, factor the numerator:

$x^3-5x^2+3x-15$

From the first two terms, factor out a x^2.

From the third and fourth terms, factor out a 3:

$=x^2(x-5)+3(x-5)$

Combine:

$=(x^2+3)(x-5)$

Putting this back:

$l=\frac{(x^2+3)(x-5)}{x^2+3}$

Cancel:

$l=x-5$

And that's our answer :)

I believe it would be D.

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and

maxonik [38]

Answer:

$10cm^2$

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

$a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm$

$b=3\frac{1}{2}=3+0.5=3.5 cm$

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid= $\frac{1}{2}(a+b)h$

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid= $\frac{1}{2}(1.5+3.5)\times 2$

Area of trapezoid= $10cm^2$
