Find the area of a rectangle with length (2x + 3) and width (x - 4). a) 2x2 - 11x - 12 b) 2x2 - 5x + 12 c) 2x2 + 11x + 12 d) 2x2 - 5x - 12

D

area of a rectangle = length × width

area = (2x + 3)(x - 4) ( expand using FOIL )

       = 2x² - 8x + 3x - 12 = 2x² - 5x - 12 → D

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
