Answer:
-7
Step-by-step explanation:
- The sum of all angles in a triangle will be equal to 180.
- So we add x+46+x+71+77=180*
- 2x+194=180
- 2x= -14
- x=-7
It depends on what kind of pencil it is.
-3(b + 9) = -9
First, divide both sides by -3. / Your problem should look like: b + 9 =
Second, simplify

to

/ Your problem should look like: b + 9 =
Third, simplify

to 3. / Your problem should look like: b + 9 = 3
Fourth, subtract 9 from both sides. / Your problem should look like: b = 3 - 9
Fifth, simplify 3 - 9 to get -6. / Your problem should look like: b = -6
Answer:
b = -6
Answer:
4x^3 + 6x^2 -10x - 15
Step-by-step explanation:
* means multiply
4x^3 + 6x^2 -10x - 15
2x * 2x^2 = 4x^3
2x * -5 = 10x
3 * 2x^2 = 6x^2
3 * -5 = -15
