Answer:
Step-by-step explanation:
<u>Coterminal angles with 117° are:</u>
- 117° + 360°x, where x is an integer
<u>When x = 1 and -1 we get:</u>
- 117° + 360° = 477° and 117° - 360° = -243°
It can be easily verified that all the other pairs are incorrect
Correct one is B
Answer:
(x-4) (x-3) (x+3)
Step-by-step explanation:
x^3 - 4x^2 - 9x + 36
Make 2 groups
x^3 - 4x^2 - 9x + 36
We can factor out x^2 from the first group and -9 from the second group
x^2 (x-4) - 9(x-4)
Now factor out (x-4)
(x-4) (x^2 -9)
This may be an answer choice but we can still factor
(x^2 -9) is the difference of squares
(x^2-9) = (x-3) (x+3)
Replacing this
(x-4) (x-3) (x+3)
Answer:
a = 9
Step-by-step explanation:
45 = 4(a + 3) – 3
Add 3 to both sides.
48 = 4(a + 3)
Divide both sides by 4.
12 = a + 3
Subtract 3 from both sides.
9 = a
a = 9
Answer: a = 9
4500(8)=36000 pounds in total
Each car weighs 4500 pounds. There are 8 cars in total.
168/12=14 feet
3 feet in 1 yard
30 feet
30-14=16 feet
