The area of a rectangle is x^2+3x-4 the width of the rectangle is x-1. determine the ratio of the area to the width

 (x + 4) : 1

Step-by-step explanation:

x² + 3x - 4 can be factored into (x + 4)(x - 1)

    Area    : width

(x + 4)(x-1) :  (x-1)

divide both sides by (x - 1) to get:

Area : width

(x + 4) :   1

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
