Answer:
The first term is 28.
Step-by-step explanation:
Given: 8th term of Geometric sequence , 
and 3rd term of Geometric Sequence, 
We have to find First term of given geometric Sequence.
Let a be the first term of geometric sequence.
We know that,

So,




So, 3rd term = 112
a × (-2)² = 112
a = 112 / 4
a = 28
Therefore, The first term is 28.
Yes. 2 squared is irrational number because no two of the same numbers multiplied equals 2. Not including decimals either.
Answer:
-10x+10y-6
Step-by-step explanation:
-4x+17-2y-6x+12y-23
-10x+17-2y+12y-23
-10x+10y+17-23
-10x+10y+-6
X^-15. This is the answer
Answer:
Step 1 and step 2
Step-by-step explanation:
she has to subtract 30 not add 30.
2(3x+6)=3(x-10)
6x + 12 = 3x-30
6x +12 - 12 = 3x - 30 - 12
6x = 3x - 42
6x - 3x = 3x - 42 - 3x
3x = -42
3x/3 = -42/3
x = -14
