Answer:
Step-by-step explanation:
x²+5x-84
look for the factors of 84 that when you add together it will give +5
look for the factors of 84 that when you multiply together it will give -84
12 and 7
addition, multiplication
-12+7 = -5 -84
-12-7= -19 84
+12-7 = +5 -84 correct
then equate into the =5x and -84
x²+12x-7x-84
then factorize
x(x+12)-7(x+12)
(x-7)(x+12)
Answer:
Step-by-step explanation:
The given function is

The graph of this function is a parabola that opens downwards
The line
intersects this parabola, when

The teammate can spike the ball after 0.25 seconds or 0.5 seconds.
The two solutions are reasonable. When the volleyball is accelerating into the air, it passes a height of 8 after 0.25 seconds.
When the ball is dropping after it attains maximum height, it attains another height of 8 after 0.5 seconds again.
The value is 4 because 4b is also 4 times three which is twelve then you divide 12 by three and get 4
