Question

. A projector displays a rectangular image on a wall. The height of the wall is x feet. The area (in square feet) of the projection is represented by x2 - 12x + 32. The width of the projection is (x - 4) feet. - a. Write a binomial that represents the height of the projection. a​

Answer 1

• We need x

$\\ \rm\rightarrowtail x(x-4)=x^2-12x+32$

$\\ \rm\rightarrowtail x^2-4x=x^2-12x+32$

$\\ \rm\rightarrowtail 8x=32$

$\\ \rm\rightarrowtail x=4ft$
