=2(y²-y-2)

=2(y²-2y+y-2)

=2[y(y-2)+1(y-2)]

=2(y-2)(y+1)

Answer:

$\boxed{x^{2} + 2x - 8}$

Step-by-step explanation:

6. Practice

The dimensions of the current park are x long and x wide.

The new park will be 4 longer and 2 thinner.

Its new dimensions will be x + 4 long and x – 2 wide.

Its new area will be

A = width × length = (x – 2)(x + 4)

Find the product

$\begin{array}{lll}\textbf{Steps} & \textbf{Problem: }(x - 2)(x + 4) & \\\textbf{1. List variables} & a = x - 2 & \\ & b = x & \\ & c = 4 &\\\textbf{2. Distribute (x - 2)} & (x -2)(x + 4)\\ & = (x - 2)(x) + (x - 2)(4)\\\textbf{3. Distribute x and 4} & x^{2} -2x + 4x - 8\\\textbf{4. Combine like terms}& x^{2} + 2x - 8\\\end{array}\\\text{The area of the updated skatepark will be }\boxed{\mathbf{ x^{2} + 2x - 8}}$

What is the slope of the line that passes through the points (-8, -3) and (-12, -3)

MA_775_DIABLO [31]

Step-by-step explanation:

slope=(y2-y1)/(x2-x1)

where (x1,y1)=(-8,-3)

(X2, y2)=(-12,-3)

slope=(-3+3)/(-12+8)=0
