A
(X-7)(x-4) -> x^2 -11x + 28
Multiply that by the 2 and you get the original equation!
S1 = 72
S2 = 12 = 72*(1/6)
S3 = 2 = 72*(1/6)^2
.
.
.
S15 = 72*(1/6)^14 = 9.18*10^(-10)
Your aqnswer is 17/12 and if u simplify it it is 1 5/12
Then a is Half of 45 wich is 22.5 I believe.
Answer:
3 x + 14
Step-by-step explanation:
Simplify the following:
6 x - 3 x - 11 + 25
Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):
(6 x - 3 x) + (-11 + 25)
6 x - 3 x = 3 x:
3 x + (-11 + 25)
25 - 11 = 14:
Answer: 3 x + 14
