Step-by-step explanation:
et the number of feet they are going to expand the width and length of the patio. ... But, we also know form our problem that they want to increase the total area of the patio by 160 ... Now we can equate the expanded area of the patio and simplify: ... Write the quadratic equation in standard form: x^2- 1 = -7x.
Side 1 = x
Side 2 = 3x+3
There are two of each side so the total is:
54 = 2(x) + 2(3x+3)
From here, just solve for x.
Certain, there’s only boys in the class so it can only be a boy chosen.
The correct answer is 6=x
