Answer:
See below.
Step-by-step explanation:
<u>Question 1</u>
a = -2 and x = -6
| a + x | / 2 - | a - x | / 2
| -2 + -6 | / 2 - | -2 + 6 | / 2
| -8 | / 2 - | 4 | / 2
8/2 - 4/2
= 4/2
= <u>2</u>
<u></u>
<u>Question 2</u>
a = -5, b = 4, c = 1, d = -3
| a - b | - | c + d |
| -5 - 4 | - | 1 - 3 |
| -9 | - | -2 |
= 9 - 2
= <u>7</u>
7x-23+11x+23=180
4x+0=180
4x/4=180/4
X=45
Answer: x=45
Volume of a Cylinder = pi * r^2 * h
V / (pi*r^2) = h
12157 / (pi * 9^2) = h = 47.774
Answer:
I think the answer is 8
Step-by-step explanation:
first you do 6 times 6
then you do 36-20
