Since Maria is going to put a trim around a triangle-shaped banner with 22 inches long per side, this means that for the banner, it has a total length of 66 inches. 66 inches would be equal to 5.5 foot. This means that the total length of the trim from the start is 7 foot. Hope this helps.
3(x + 8) = 17....distribute the 3 thru the parenthesis 3x + 24 = 17...subtract 24 from both sides 3x = 17 - 24 3x = -7...divide both sides by 3 x = -7/3 or -2 1/3 <===
