Answer:
Expressions below
Step-by-step explanation:
1) (x³ - 7) ÷ (x + 2)
(x³ + 2x² - 2x² - 4x + 4x + 8 - 8 - 7) ÷ (x + 2)
[x²(x + 2) - 2x(x + 2) + 4(x + 2) - 15] ÷ (x + 2)
= (x² - 2x + 4) - 15/(x + 2)
2) (2x³ - 3x² - 17x + 30) ÷ (x + 3)
= [2x³ + 6x² - 6x² - 3x² - 10x + 10x - 17x + 30] ÷ (x + 3)
= [2x³ + 6x² - 9x² - 27x + 10x + 30] ÷ (x + 3)
= [2x²(x + 3) - 9x(x + 3) + 10(x + 3)] ÷ (x + 3)
= 2x² - 9x + 10

Answer:
The answer is 2
Step-by-step explanation:
To find this, follow the order of operations as laid out below.
120(2x - 2) = 240 ----> Divide both sides by 120
2x - 2 = 2 ----> Add 2 to both sides
2x = 4 ------> Divide both sides by 2
x = 2
