Which of these is most likely to describe the number of yards lost in a football game? A. Rational Number
B. Whole Number
C. Real Number
D. Integer

D

Step-by-step explanation:

Well, first of all, all the yards in football are numbers like 4, or -5, etc. This is not a whole number for it is a whole, not like 1/2. Because the number of yards lost can also be negative. 1/2 is a rational number. A real number is simply not a thing. An integer means it can be positive or negative, so that is the correct choice.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
