Area is calculated by multiplying length by width. Since we are given the width, we can test each length and see if the product matches the rectangle's area.

(2m - 3)(4m - 4) = 8m² - 20m + 12 ≠ 8m² + 4m - 12

(8m - 3)(4m - 4) = 32m² - 44m + 12 ≠ 8m² + 4m - 12

(2m + 3)(4m - 4) = 8m² + 4m - 12

(8m + 3)(4m - 4) = 32m² + 20m - 12 ≠ 8m² + 4m - 12

The length of the rectangle must be 2m + 3. Another method of solving this would be to divide the area by the width, or 8m² + 4m - 12 ÷ 4m - 4.

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6

vodka [1.7K]

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial $-3x^4+2x^3-x^2+6$ through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial $-3x^4+2x^3-x^2+6$ .
