The formula for the area of a rectangle is A = L(length) × W(width) A = L × W Plug in the information: A = 44, L = 2W - 3 b/c less than means switch the order before subtracting, W = W 44 = (2W - 3)×W 44 = 2W² - 3W ← used the distributive property... This is a quadratic equation 2W² - 3W - 44 = 0 ← collect all terms on one side so we can use some method to solve a quadratic equation... like factoring or quadratic formula Note any negative values will be discarded because dimensions are measurements and they are not negative
Factoring: (2W - 11)(W + 4) = 0 2W - 11 = 0 solves to W = 5.5 W + 4 = 0 solves to W = -4 ←must discard So W = 5.5 and L = 2(5.5) - 3 = 8 You can check the values to see if they equal 44 when plugged into Area formula ANSWER: Dimensions 8 ft by 5.5 ft
The mean is <span>1995 you have to add all them together 2046+971+3113+1850=7980 then you divide it by 4 because there are 4 numbers and you are left with </span>1995 Hope this helped :)
