Answer:
10 yards is the answer
Step-by-step explanation:
2(2x+3)+2x=27
6x+6=27
6x=21
×=31/2
31/2×2+3=10
Answer: I think the answer is (4,-3)
Step-by-step explanation:
H(x) = 16 - x
plug -4 in as x
H(x) = 16 - (-4)
solve 16 - (-4)
H(x) = 20
your answer is A)20
Trapezoids ^_^ the above were all parallelograms with two pairs that are parallel, while a trapezoid only has one pair of parallel sides
Lets go ahead and calculate the area of each side; added together, this will give us the full surface area. First the base, which is 9 by 9 and a square. This means its area is 9*9, which equals 81. Next the triangles, which are all the same, so we only have to do it once and then add it 4 times at the end. The area of a triangle is (1/2)bh, so (1/2)(9)(7) = 31.5.
Finally, we just need to add the areas up.
81 + 31.5 + 31.5 + 31.5 + 31.5 = 81 + 4(31.5)
81 + 126 = 207 units^2
