The answer to (a)(b)(c) is 2,656
Mr Jones typed 40 * 10 = 400 words.
Mrs Gonzales took 400 / 50 = 8 minutes to type same number of words.
The difference of seven and two tenths and a number is more than twenty nine.
7.2 -n >29
Choice A
The terms 9r^2 and 6r^2 are like terms. We add the numbers to the left of the "r^2" to get 9+6 = 15.
So 9r^2+6r^2 becomes 15r^2
The r^2 stays the same. We do not say something like r^2+r^2 = r^4. You might be thinking of r^2 * r^2 = r^(2+2) = r^4
When it comes to adding like terms, we keep the variables the same.
The other pair of like terms are 3r and 2r, so they add to 3r+2r = 5r
--------------------------------------------------------------------------------------------
Overall,
(9r^2+3r+6)+(6r^2+2r) = (9r^2+6r^2)+(3r+2r)+6
(9r^2+3r+6)+(6r^2+2r) = 15r^2+5r+6
