Find the area of the following shape. You must show all work to receive credit.
Svetach [21]

Answer:

8

Step-by-step explanation:

Split up the shape into three smaller shapes: a triangle at the top, a 1 by 2 rectangle, and a triangle at the bottom left. The 1 by 2 rectangle has an area of 2. The triangle at the top has an area of (4*2)/2 = 4, and the triangle at the bottom right has an area of (2*2)/2 = 2.

Therefore, the total area of the shape is 2 + 4 + 2 = 8

Hope this helped!

A company offers premium cable for 39.95 per month plus a one time setup fee. The total cost of 6 months of service is 264.70. W
ss7ja [257]

Answer:

Total cost = 983.8

Step-by-step explanation:

Monthly charge = 39.95

One time set up fee = x

Number of months = y

Total cost = x + 39.95y

The total cost of 6 months of service is 264.70.

264.70 = x + 39.95(6)

264.70 = x + 239.7

264.70 - 239.7 = x

x = 25

Total cost = 25 + 39.95y

Write and solve a linear equation to find the total cost for 2 years of service

2 years = 24 months

Total cost = 25 + 39.95y

= 25 + 39.95(24)

= 25 + 958.8

= 983.8

Total cost = 983.8
