Danny bought a book and a game the book costs x$ and the games costs 3 times as much as the book how much money did danny spend

$4x

Step-by-step explanation:

Cost of book = $x

Since the games costs 3 times as much as the book, therefore, the cost of the game will be: = 3 × $x = $3x

Therefore, the amount of money that Danny spent to buy the book and the game will be the addition of the cost of the book and the game. This will be:

= $x + $3x

= $4x

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
