A rectangle with a length of x+2 cm has an area of 4x⁴-18x²-6x-4 sq. cm. Write a polynomial the represents its width Answer: 4x³ - 8x² - 2x - 2 Step-by-step explanation: Given: length of x+2 cm area of 4x⁴-18x²-6x-4 sq. cm Ask: width Solution: A = L x W 4x⁴-18x²-6x-4 sq. cm = (x+ 2 cm) W 4x⁴-18x²-6x-4 sq. cm = (x+ 2 cm) W X + 2 cm x + 2 cm 4x³ - 8x² - 2x - 2 = W So , the width is 4x³ - 8x² - 2x - 2.
