Answer:
√52 units
Step-by-step explanation:
The segment MN is the hypotenuse of a right triangle that is 6 units wide and 4 units high. The Pythagorean theorem tells you its length is ...
MN = √(6² +4²) = √(36 +16)
MN = √52
I got C. -14x - 2
I might be wrong
1.) Group like terms: 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x-5+7
2.) Add similar elements: = 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x=0
3.) =-5+7
4.) Add/Subtract the numbers: -5 + 7 = 2
<u>Your Answer: 2</u>
To get your answer:
9 times 5 times two= 90
9 times 7.5 times two= 135
5 times 7.5 times two= 75
then add all of them together and you will get the surface area
90+135+75=300
you should have an answer of 300 feet²
