Answer:
my answer for is number 61
Step-by-step explanation:
Thats all I know.
I believe it would be the second one. That is two 90 degree rotations to add up to a 180 degree rotation.
Answer:
The one on top is y^8 - 1/y^8 (option 1)
The one on the bottom is 1/y^8 + 1/y^2 (option 5)
Area of a trapezoid is height times the average of the bases,
A= 1/2 h (a + b)
Here we have height h=12 and bases a=30, b=12 so area
A = (1/2) (12) (30 + 12) = 6(42)= 252
Answer: B
L = 2 + .5W
2L + 2W = 40
SOLVING (if needed)
Substitute 2 + .5w in for l in the second equation and solve for w.
2(2 + .5w) + 2w = 40
4 + w + 2w = 40
Combine like terms and subtract 4 from both sides
3w = 36
Divide both sides by 3
w = 12 in.
l = 2 + .5w
l = 2 + .5(12)
l = 8 in.
