A) constant=40, coefficient=7.50, variable=h
B)7.50h+.20s+40
7.50(25)+.20(300)+40
187.5+60+40=287.5$
C)9.0h+.2s+40, So yes a coefficient would change, but nothing else
Answer: D.
Step-by-step explanation:
Water is continually pumped out of underground aquifers to prevent flooding and to provide drinking water. This makes the soil compact, causing the city to sink.
x^2−17x+30=0
Step 1: Factor left side of equation.
(x−2)(x−15)=0
Step 2: Set factors equal to 0.
x−2=0 or x−15=0
x=2 or x=15
