Answer:
10+4x
Step-by-step explanation:
COmbine like terms
4x + 10
3 + 4x + 7 = 4x + 10
242/27
Using the formula for the sum, you can fill in the given values and do the arithmetic.
Sn = a1·(r^n -1)/(r -1)
S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)
S5 = 242/27
_____
Or, you can write the terms and add them up. The sum is ...
6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27
i really hope this helps
x²+7x-11=-5x+6
x²+7x+5x-11-6=0
x²+12x-17=0
