Answer:
A
Step-by-step explanation:
The formula for the perimeter is 2l +2w. 4x^2+4x^2=8x^2. y^2+y^2=2y^2.
If we add them together the answer is 8x^2+2y^2.
Answer:
3.75
Step-by-step explanation:
Answer:
- 4. -3
- 5. -1/2
- 6. 1/2
- 7. 4
- 8. 0
- 9. undefined
Step-by-step explanation:
<u>Use of slope formula:</u>
4.
- m = (7 - 4)/(1 - 2) = 3/-1 = -3
5.
- m = (-2 - 0)/(3 - (-1)) = -2/4 = -1/2
6.
- m = (5 - 3)/(5 - 1) = 2/4 = 1/2
7.
- m = (3 - 0)/(3.5 - 4.25) = 3/0.75 = 4
8.
- m = (3/4 - 3/4)/(5 - 2) = 0
9.
- m = (2 - 3)/(7.5 - 7.5) = -1/0 = undefined
