AHH, What is this? and plz explain THX <3

The maximum height of an ad that the company can afford is 20 inches.

Step-by-step explanation:

2,050 = 50 + 10(h * w),

where h is height, w is width and h = 2w.

2,050 = 50 + 10(h * w)

(subtract 50 from each side)

2,000 = 10(h * w)

(divide each side by 10)

200 = h * w

(substitute 2w for h)

200 = 2w * w

(divide each side by 2 and simplify)

100 = w * w

100 = w²

(find the square root of each side)

10 = w

So if the width is 10, then since the height is twice the width, then the height has to be 20.

what is the graph

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
