Answer:
a.) 
Step-by-step explanation:
Find two numbers that add up to -6 and multiply to -40 (you will most likely need a negative and a positive because -40):
-10 and 4
Factor:
Finito.
So what we do first is find out the cost per foot which is 305÷154=1.9805194805194805195
Then we find out the area of the second rug which is 288 feet and multiply that by the cost 1.9805194805194805195. We then get 1.9805194805194805195x288=570.38961038961038961
1/6x = 2.....multiply both sides by the reciprocal 6/1
(6/1)(1/6)x = 2(6/1)
1x or just x = 12
Answer:
416 mi
Step-by-step explanation:
In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.
<em>Remember to find the area it is length x width</em>
- 9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
- Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
- In total, you will add 72+72+72+72+64+64 which equals 416
