Homer and Bart plan to buy one computer for $499.00 quickly for gaming purpose games cause $49.00 each

Alright, we know that we have to spend 499 dollars on a computer as a base cost. Next, we have to buy 49.99 * x dollars worth of games (since games are 49.99 each), adding up to 499+49.99*x

Alright, so plugging 5 in for x, we get 499+49.99*5=744.95

Since one controller is 24.99, the money for buying a y amount of controllers would be 24.99*y., making the expression 499+49.99x+24.99y

Since in part D, there are no games, we plug these in to get  

499+49.99*0++24.99*3=573.97 dollars

Step-by-step explanation:

hi there!

the answer will be d: 2

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
