Answer:
k = 10
Step-by-step explanation:
The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.
So 10k + 15 must equal the remaining 115
subtract 15 from each side and you get 10k = 100
divide each each by 10 and you get the answer of k = 10
Answer:
3
Step-by-step explanation:
Let the width of the coop be x. Then the height is x - 2, and the length is x + 10. Then the volume of the coop (a rectangular prism) is:
y = x(x-2)(x+10) = x^3 + 8x^2 - 20x
Based on the given format, this means that:
a = 1
b = 8
c = -20
d = 0
