Answer:
3
Step-by-step explanation:
The coordinates of B ( 4,0)
The coordinates of C = (5,3)
The slope is
m = (y2-y1)/(x2-x1)
= (3-0)/(5-4)
= 3/1
= 3

Answer:
(x + 4)² - 4 = 0
Step-by-step explanation:
Given
x² + 8x + 12 = 0
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 8x
x² + 2(4)x + 16 - 16 + 12 = 0
(x + 4)² - 4 = 0
189 inches is 15.75 feet
16 ft - 15.75 ft = 0.25 ft
0.25ft = 3 inches
He must vault 3 inches higher
