Question

Which of the following represents the area of a rectangle whose length is 3x - 7 and whose length is
x + 2

Answer 1

3x2 - 14
3x2 + x - 14
3x2 - x - 14
3x2 + 14

Answer 2

Area = L * W
so multiply (3x-7)*(x+2)

Answer 3

does that help?
Im assuming you meant one of those to be width

Answer 4

wait so which one is it?

Answer 5

so foil out (3x-7)*(x+2)
do you know how to do that?

Answer 6

no this is an assignment that i have to do to see if I know any of the material im going to learn in this unit. Ive never come across this stuff before.

Answer 7

is it D?

Answer 8

well the area of any rectangle is the height times the width. those terms you have represent the height and the width of the triangle so
(3x-7)*(x+2)=(3x^2-7x+6x-14)
3x^2-x-14

Answer 9

ohhhhh. i kinda see what you did there. thankyou!
