Step-by-step explanation:
(0,7) is a point on the y-axis
the function intercepts the y-axis at (0,7)
when the y = 7
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
To find a perimeter add all the sides of the shape. so 12+9+15 is 36. the perimeter of the triangle is 36
