Answer:
A. 6.681.060.239
Step-by-step explanation:
a1 = 7
r = (-8)
n= 11
S11 = 7((-8)^11 - 1)/ (-8-1)
= -7/9 ( -8,589,934,591)
= 6.681.060.239
Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90
Answer:
B. 
Step-by-step explanation:
Let
, we proceed to find its equivalent expression by applying logarithm properties:
1)
Given.
2)
Definition of logarithm.
3)

4)

5)
Compatibility with addition/Existence of additive inverse/Modulative property
6)
Symmetrical property/Result.
Hence, the right answer is B.
Step-by-step explanation:
5x – 2x + 7 – x = ?x + ?
I need the answer for "no solution" and "infinite solutions".
NO SOLUTION:
no solution because any value you give to x is not solvable, it remains +7
5x – 2x + 7 – x = ?x + ?
2x = 2x + 7
INFINITE SOLUTION
infinite solutions because any value you give to x is solvable
5x – 2x + 7 – x = ?x + ?
5x – 2x + 7 – x = 2x + 7
2x + 7 = 2x + 7
