The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
-5(-1-2)
5+10
15
Or
-5(-1-2)
-5(-3)
15
It's 15 either way.
Answer: 4a
<u>Step-by-step explanation:</u>
12a²b⁶ 28a⁴ 42ab³
∧ ∧ ∧ ∧ ∧ ∧
2 6 a² b⁶ 7 4 aaaa 7 6 a b³
∧ ∧ ∧ ∧ ∧
2 3 aa bbbbbb 2 2 2 3 bbb
12a²b⁶: 2 * 2 * 3 * aa * bbbbbb
28a⁴: 2 * 2 * 7 * aaaa
42ab³: 2 * 2 * 3 * 7 * a * bbb
What do they have in common? two 2s and one a
GCF = 2 * 2 * a = 4a
A negative answer could mean that u owe someone money...or u still owe on a previous balance
Answer: 352/105
Step-by-step explanation:
Diameter of the circular disk is
(2−x2)−x2
so that the radius of the disk is the diameter divide by 2
(2−x2−x2)/2.
Integrating V at 1 and -1, we get
V =Z 1−1A dx =Z 1−1π(1 − x2)2
dx = π(x −2/3x3 +1/5x5)1−1
=16/15π
= 352/105
