Answer:
The area of the shape (trapezoid) is 55 square feet.
Step-by-step explanation:
The formula to get the area of a trapezoid is 
. b1 is one of the bases, b2 is the other and h is the height.
First, you need to find the average of the bases:
(15+7=22)/2=11
Then, you multiply that by the height.
11*5=55
Lastly, you add the units.
55 square feet is the answer
Is there supposed to be an image? Adjacent is adjoining, so like touching each other. Vertical is "up". Horizontal is "side"
(2,6) it’s where they cross. If there isn’t a graph make the two equations equal to each other to find x then plug in x to either equation to find y
1,296.0 I think this is right, I apologize if it’s wrong.
An = -4 + (n - 1)(7)
This being in the form of the explicit rule for an arithmetic sequence you can pick out the d and a1.
an = a1 + (n - 1)(d)
d = 7
a1 = -4
