Answer: 142 sq. ft
Step-by-step explanation: decompose the figure into two figures. Then, find the length and the width of each figure and find their separate areas. Lastly, add the two areas together to get the total area.
Answer:
x = - 3
Step-by-step explanation:
Given
12x + 7x = 5x - 42, that is
19x = 5x - 42 ( subtract 5x from both sides )
14x = - 42 ( divide both sides by 14 )
x = - 3
F(X)=13 Just Plug 10 into the X in the equation
Answer:
4.8 feet
Step-by-step explanation:
Answer:
A. 0.72
Step-by-step explanation:
When the ball hits the ground, h = 0.
0 = -16t² + 6t + 4
0 = 8t² − 3t − 2
Solve with quadratic formula:
t = [ 3 ± √(9 − 4(8)(-2)) ] / 16
t = (3 ± √73) / 16
t = 0.72
