Answer:
- 2x² + 7x + 1
Step-by-step explanation:
f(x) - g(x)
= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1
= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms
= - 2x² + 7x + 1
Answer:
n=27
Step-by-step explanation:
The answer is a
Explanation: I’m not too sure about it
(x + 7) (x - 4)
First, apply the FOIL method (a + b) (c + d) = ac + ad + bc + bd / Your problem should look like:

- 4x + 7x - 28
Second, gather the like terms. / Your problem should look like:

+ (-4x + 7x) - 28
Third, simplify. / Your problem should look like:

+ 3x - 28
Answer:
+ 3x - 28
7/9
Since the probability of getting a 1 or 9 is 2/9
9-2=7
so 7/9
