Answer:
Step-by-step explanation:
6x³ and (-5x³) are like terms
y² and 2y² are like terms
Combine like terms
6x³ + y ² - 5x³ + 2y² = 6x³ - 5x³ + y² + 2y²
= x³ + 3y²
∠a:
m∠a + 50 = 180 (because they are supplementary angles)
m∠a + 50 (-50) = 180 (-50)
m∠a = 180 - 50
m∠a = 130°
-------------------------------------------------------------------------------------------------------------------
m∠d + 65 + 50 = 180
m∠d + 115 = 180
m∠d + 115 (-115) = 180 (-115)
m∠d = 65°

Answer:
![\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]](https://tex.z-dn.net/?f=%5CSigma_%7Bk%3D1%7D%5E%7Bn%7D%5B3%28%5Cfrac%7B10%7D%7B9%7D%20%29%5E%7Bk-1%7D%5D)
Step-by-step explanation:
A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.
The first term is denoted by a and the common ratio is denoted by r.
A geometric sequence has the form:
a, ar, ar², ar³, . . .
The nth term of a geometric sequence is 
Therefore the sum of the first n terms is:
Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:
