I think it might be D. I'm just giving an educated guess.
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.

, multiplied by the last "x+y".

Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of

, 3 comes in front of

, 3 comes in front of

, and 1 comes in front of

.
Thus: 1, 3, 3, 1.
Answer Choice A
Answer:
5,280 * 8 = 42,240
42,240 feet
42,240 * 12 = 506,880
506,880 inches
Step-by-step explanation:
Perimeter: all the sides added together, so that would be 1/2+1/2+3/4+3/4, which is 2 and a half feet
Area: the two side lengths multiplied, so 1/2*3/4, which is 3/8 feet squared
Answer:
58
Step-by-step explanation:
all triangles add up to 180 degress
180-64=116
because its an isosceles triangle divide by two
116/2=58
