The painter painted 11 apartments because 4 doesn’t go into 45, so the closest think to 45 is 4 x 11 (44). the painter will have 1 gallon left.
4(r)^x=y
4(r)^(1)=2
r=1/2
y=4*(1/2)^x
Alright. (1/4^2)+2((1/4)(2/3)-3(2/3^2)=-.9375 is the correct answer
Assuming the side lengths did not change, ...
Angle C would need to decrease by the same amount.
Angles B and D would each need to increase by the amount angle A decreased.
