Please help

$0.00, $0.50, $1.00, $1.50, $2.00, $2.50, $3.00, $3.50, $4.00, $4.50, $5.00, $5.50

Step-by-step explanation:

Just add .50 (cents) on every time. When it comes to dollar notation, it should be marked with the dollar sign in front, and then the dollar amount, and then a decimal and the cent amount. The cent amount would be to the hundreths.

Blank 1 = .50

Blank 2 = 2.50

Blank 3 = 3.00

Blank4 = 4.00

Blank 5 = 4.50

Blank 6 = 5.50

Step-by-step explanation:

Add or subtract .50

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
