Henry has two same size rectangle divided into the same number of equal parts.one rectangle has 2/5 of the parts shaded,and the other has 1/2 of the parts shaded. into how many parts could each rectangle be divided? show the work

(1)       x  (x+ 3) - 4 (x +3) = 0

(2)        x = 4                 and       x = -3

Step-by-step explanation:

given data

equation

(x−4)(x+3)=0

solution

given equation  (x−4)(x+3) = 0

equation as a compound statement is

x  (x+ 3) - 4 (x +3) = 0

and

two solutions to the equation are

so x  (x+ 3) - 4 (x +3) = 0

x- 4 = 0           and        x + 3   = 0

x = 4                 and       x = -3
