Select all expressions that are equivalent to x2 - 4x - 32.

Nikitich [7]

Answer:

(x - 8)(x + 4)

(x + 4)(x - 8)

Step-by-step explanation:

(x - 16)(x + 2)

= x2 + 2x - 16x - 32

= x2 - 14x - 32

(x + 2)(x - 16)

= x2 - 16x + 2x - 32

= x2 - 14x - 32

(x - 8)(x + 4)

x - 8)(x + 4) = x2 + 4x - 8x - 32

x - 8)(x + 4) = x2 + 4x - 8x - 32 = x2 - 4x - 32

( 30 + x)(x - 4)

= 30x - 120 + x2 - 4x

= x2 + 26x - 120

(x + 4)(x - 8)

(x + 4)(x - 8) = x2 - 8x + 4x - 32

(x + 4)(x - 8) = x2 - 8x + 4x - 32 = x2 - 4x - 32

(x - 4)(x + 8)

= x2 + 8x - 4x - 32

= x2 + 4x - 32

What is the slope of a line that passes through the points (-2, 4) and (-6, 12)?

SOVA2 [1]

We can use the formula y2-y1/x2-x1 to find the answer. Therefore, we have: 12-4/ -6-(-2). That gets us 8/-6+2 = 8/-4= -1/2. The answer is 3.
