PLS HELP A parallelogram is shown below: A parallelogram ABCD is shown with DC equal to 9 feet and the perpendicular distance between AB and DC equal to 8 over 9 foot. Part A: What is the area of the parallelogram? Show your work. (5 points) Part B: How can you decompose this parallelogram into two triangles? If this parallelogram was decomposed into two triangles, what would be the area of each triangle? (5 points)

See below

Step-by-step explanation:

Part A:

area of parallelogram = base * height

A = 9 ft * 8/9 ft = 8 ft^2

Part B:

Connect point D to point B with a segment. Now you have 2 triangles.

The area of each triangle is base * height/2

area of triangle = bh/2 = (9 ft)(8/9 ft)/2 = 4 ft^2

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
