Answer:
2a² + a ( or a(2a+1) )
Step-by-step explanation:
(6a²+3a) - (4a² + 2a) (expand parentheses)
= 6a²+3a - 4a² - 2a (group like terms)
= 6a²- 4a²+3a- 2a
= 2a² + a
= a(2a+1)
Answer:
21

bc 9+10
Answer:
x = 10
Step-by-step explanation:
We would use postulates and theorem to figure out 34 = 3x + 4. Once you set 34 equal to 3x + 4, you would solve for x as can be shown below:
34 = 3x + 4
Subtract 4 from both sides.
30 = 3x
Divide both sides by 3.
10 = x
This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
