Answer:
x^3 + 3x^2 + 2x = x(x^2 + 3x + 2)
= x(x^2 + x + 2x + 2)
= x(x(x+1) + 2(x+1))
=x(x+1)(x+2)
Hope this helps!
Answer:
a₆ ≈ 25.284
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
8 ÷ 6 =
÷ 8 = ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
This indicates the sequence is geometric with nth term
= a₁ ![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a₁ is the first term and r the common ratio
Here a₁ = 6 and r =
, then
a₆ = 6 ×
= 6 ×
=
≈ 25.284 ( to the nearest thousandth )
- 2x and 70 are equal, because they are vertical angles.
- 110 and 3x + 5 are equal, becasue they are vertical angles.
- so, the answer would be A.
-- this is because vertical angles are not supplementary so would not be equal to 180°
the plus sign (+) means above seal level
so the sign should say 2100 feet above sea level
Tbh, honestly, u just gotta prove the congruence, your welcome
