Answer:

Step-by-step explanation:

The opposite angles of the quadrilateral are supplementary, thus

x + 10 + 70 = 180

x + 80 = 180 ( subtract 80 from both sides )

x = 100 → A

What is the midpoint of line segment AB?

Elza [17]

Answer

Midpoint = (3, 5.5)

Step by step explanation

Here we have to use the midpoint formula.

Midpoint = ( $\frac{x1 + x2}{2} , \frac{y1 + y2}{2} \\$ )

Here the point A = (-1, 8) and B = (7, 3)

x1 = -1, y1 = 8, x2 = 7 and y2 = 3

Now plug in these values into the formula.

Midpoint = ( $\frac{-1 + 7}{2} , \frac{8 + 3}{2}$

= (6/2, 11/2)

= (3, 5.5)

Therefore, the midpoint the line segment AB is (3, 5.5)

Thank you.

Multiply.

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.
