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
V = (4/3)×3.14×(1.5^3)
V = 14.1 in^3
Answer:
x=4
Step-by-step explanation: So you do 2x plus 1x which is 3x. Then you divide both sides by 3 which leaves you with x=4. Thats your answer. <3
Answer:
Yes
Step-by-step explanation:Because it has 6 sides
