Answer:

D) 2x² + 4x - 30

Step-by-step explanation:

Follow the FOIL method:

FOIL =

First

Outside

Inside

Last

...and is the order you multiply to solve:

(x + 5)(2x - 6) =

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Combine like terms. Simplify:

2x² -6x + 10x - 30 = 2x² (-6x + 10x) - 30 = 2x² + 4x - 30

2x² + 4x - 30 is your answer.

Answer:

(-1,-1)

Step-by-step explanation:

Midpoint equation: $(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})$

= $(\frac{-5/2+1/2}{2},\frac{-1/2-3/2}{2} )$

= $(\frac{-2}{2},\frac{-2}{2})$

=(-1,-1)

Use the formula and plug it in :)
