Answer:
a x (a2-2)
Step-by-step explanation:
the 2 is supposed to be above the a I don't know how to that while typing.
22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)
22.5 = X - 7.5 《 This is the equation.
Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30).
Amplitude: 1/4 (= |a|)
Frequency: 1/2 (= |b|)
Period: 4pi (= 2pi/|b|)
<span>There are 8 pints in 1 gallon, so 3 pints is 3/8 of a gallon </span>
