Find the measure of angle D, and the perimeter and area of parallelogram abcd
Alecsey [184]

Answer:

It is the last choice.

Step-by-step explanation:

m < D = 180 - 28 = 152 degrees ( as same side angle add up to 180 degrees).

The perimeter = 2*17 + 2*25 = 84 cm ( as opposite sides of a parallelogram are congruent).

The area = base * height = 8 * 25

= 200 cm^2.

How do you solve −2x−4=3x+1 by graphing
crimeas [40]

Answer:

Step-by-step explanation:

You first have to simplify...

-2x-4=3x+1 (-1 both sides)

-2x-5=3x (+2x both sides)

-5=5x

-1=x

So graphing that would be a vertical line on -1.
