Answer:

\frac{(2x-3)(x+7)}{x+3}

Step-by-step explanation:

Given

\frac{2x^3+11x^2-21x}{x^2+3x}

Required

Select equivalent expression

\frac{2x^3+11x^2-21x}{x^2+3x}

Factorize the numerator and denominator

\frac{x(2x^2+11x-21)}{x(x+3)}

Divide by x/x

\frac{2x^2+11x-21}{x+3}

Expand the numerator

\frac{2x^2+14x-3x-21}{x+3}

Factorize the numerator

\frac{2x(x+7)-3(x+7)}{x+3}

\frac{(2x-3)(x+7)}{x+3}

Hence, the equivalent expression is:

\frac{(2x-3)(x+7)}{x+3}

Answer:

13\frac{1}{3}\ in

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

step 1

Find the scale factor

Let

z ----> the scale factor

z=\frac{10}{6} ----> ratio of corresponding sides

simplify

z=\frac{5}{3}

step 2

Find the length of the enlarged design (L)

Multiply the length of the original design by the scale factor

so  

L=\frac{5}{3}(8)=\frac{40}{3}\ in

Convert to mixed number

\frac{40}{3}\ in=\frac{39}{3}+\frac{1}{3}=13\frac{1}{3}\ in

i need to find the distance between the points,round to the nearest tenth show work please this is my last question!!
natka813 [3]

Answer:

4.2 units

Step-by-step explanation:

Assuming 1 grid box = 1 units, the coordinates of the two points are (-1, -1) and (2, 2).

Apply distance formula d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} to find the distance between (-1, -1) and (2, 2).

Let,

(-1, -1) = (x_1, y_1)

(2, 2) = (x_2, y_2)

Plug in the values

d = \sqrt{(2 - (-1))^2 + (2 - (-1))^2}

d = \sqrt{(3)^2 + (3)^2}

d = \sqrt{9 + 9}

d = \sqrt{18}

d = 4.2 (to the nearest tenth)
