Gaming a video-game designer is using the expression 6n3 in a program to determine points earned, where n is the game level.
Given expression is . the given expression is for the nth level.
To simplify the expression for the level, we plug in
in the place of 'n' in the given expression
(multiply the exponents)
X(x + 3) + 34 = (x + 5)(x + 2)
First, expand to remove parentheses.
Second, add '2x + 5x' to get '7x'.
Third, cancel out '
' on both sides.
Fourth, subtract '3x' from both sides.
Fifth, subtract '7x - 3x' to get '4x'.
Sixth, subtract '10' from both sides.
Seventh, subtract '34 - 10' to get '24'.
Eighth, divide both sides by '4', leaving the 'x' by itself.
Ninth, since '24 ÷ 4 = 6', simplify the fraction to '6'.
Tenth, switch your sides to get the answer.
Answer: x = 6
