Answer:
D)
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4
Answer:
D is the answer

Answer:
Step-by-step explanation:
Joint variation problem solve using the equation y = kxz.
e ∝ fg
e=kfg
now substitute the values
The relationship will be:
Let x = times in the pool
Let y = times in the basketball courts
42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x
The person used the pool 9 times.
