Answer: I think D. Let me know if I’m right!
I think it’s C but i’m not sure
Set it up in a proportion.
8 (oil)/5 (salad dressing) = x/7
cross multiply to get 11.2
X^2-16 is a difference of squares of the form:
(a^2-b^2) which always factors to:
(a+b)(a-b), in this case we have:
(x+4)(x-4), we are told that width is (x+4) so the length is:
(x-4)
