Bree wants to buy a new wall unit for her living room. The wall unit measures display on the Better Homes magazine was 3 inches wide and 7 inches tall. What would the actual wall unit measurements be if the scale is 2 inches: 4 feet? ( your response should be # wide by # tall).

6 inches wide and 14 inches tall .

Step-by-step explanation:

Given : For wall unit measures display,

width = 3 inches

height = 7 inches

Scale used = 2 inches: 4 feet

So, 1 inch = 2 feet  [divide both sides by 2]

That means, actual width of wall unit = 3 x 2 inches = 6 inches

Actual height of wall unit = 7 x 2 inches = 14 inches

hence, the actual measurements of wall unit are 6 inches wide and 14 inches tall .

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
