let X = the area of the smaller rectangle X / 85 = 3 / 5 X = (85)(3/5) X = 51 The area of the smaller rectangle is 51 square feet. that's it! ;)

since 4+i is a root, its conjugate, 4-i must also be a root. So you have 3 roots, which means 3 factors: (x - 2) (x - 4 - i) (x - 4 + i) multiply these out and you have your cubic equation: y = (x-2)(x² - 8x - 16) y = x³ -10x² + 32 …

To solve for x, first eliminate the exponent by taking both sides to the 3/2 power. Now you have, x+3 = 8^(3/2). Next subtract 3 from both sides. x = 8^(3/2) -3 You can put that into a calculator for an approximate answer of 19.6. Or …
