Answer:
x = -3
Step-by-step explanation:
2(x + 7) - 3 = 5 (given)
2x + 14 - 3 = 5 (Distributive Property)
2x + 14 = 8 (Addition Property of Equality)
2x = -6 (Subtraction Property of Equality)
x = -3 (Division Property of Equality)
5x + 20 because rise over run 5 over 1 so its 5x and 20 is on the y intercept line
Step-by-step explanation:
Answer:
x³ - 3x² - 18x
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ
Now, for the given:
To solve thus question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final answer.
This can be done as follows:
(x + 3)(x² - 6x)
x(x²) + x(-6x) + 3(x²) + 3(-6x)
x³ - 6x² + 3x² - 18x
x³ - 3x² - 18x
Hope this helps :)
