Hope this helps but I think the answer is $8.91.
For each question we must apply the Pythagorean theorem and clear the value of x.
question 5
x = root (14 ^ 2 + 16 ^ 2)
x = root (452)
x = 2raiz (113)
question 6
x = root (8 ^ 2 + 15 ^ 2)
x = 17
question 7
x = root (12 ^ 2 + 12 ^ 2)
x = root (2 * (12 ^ 2))
x = 12raiz (2)
question 8
x = root (18 ^ 2 - 9 ^ 2)
x = root (243)
x = 9raiz (3)
The answer is A hope this helped you
U have the to use the formula
y2-y1/x2-x1
that will get u the slope
-10-8 = -18
-9-1= -10
this give u 18/10 which can be simplified to 9/5
so the slope is 9/5
hope this helps!
So, 27=30 and 18=20 rounded
so what you would do now is multiply 30 x 20 and you get $600
