The length of a rectangular field is represented by the expression14x-3x^2+2y. the width of the field is represented by the expression 5x-7x^2+7y. how much greater is the length of the field than the width? a) 9x+4x^2-5y b)9x-10x^2-5y c)19x+4x^2+9y d) 19x-10x^2+9y

i believe the answer is letter c) 8

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
