Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units? A. f(x) = 2x2 – 4x + 4 B. f(x) = 2x2 + 8x – 4 C. f(x) = 2x2 – 8x + 4 D. f(x) = 2x2 − 2x − 4

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

i think its a and d

step-by-step explanation:

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
