Answer:
6
+ 5x² - 2x + 3
Step-by-step explanation:
Given
(
+ 2x² - 4) - (-5
- 3x² + 2x - 7)
Remove the parenthesis on the first factor and distribute the second by - 1
=
+ 2x² - 4 + 5
+ 3x² - 2x + 7 ← collect like terms
= 6
+ 5x² - 2x + 3 ← in standard form
Answer:
3x + 2 - 3x + 7 + 5x = 5x + 9
Step-by-step explanation:
The coefficient is 5.
Answer:
2
Step-by-step explanation:
2 is the answer because the circle touches the line only 2 times.
Hope this helps.
|2x + 12| = 18
First, break down the problem into 2 equations . / 2x + 12 = 18 and -(2x + 12) = 18
Second, solve the first equation. /

Subtract 12 from both sides. /

Subtract 18 - 16. /

Divide both sides by 2. /

Simplify. /
Third, solve the second equation. / -(2x + 12) = 18
Simplify your brackets. /

Add 12 to both sides. /

Add 18 + 12. /

Divide both sides by -2. /

Simplify. /

Simplify. /
Fourth, collect the solutions. /

Answer:
x = -15, 3
