Answer:
Step-by-step explanation:
Distribute negative sign.
Combine like terms.
An=3*(4^(n-1)) is the explicit
the recursive is <span>t_n = 4 * t_(n-1)</span>
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Answer:
f(3) = 9
Step-by-step explanation:
In the given figure,
when x=3,
f(x)=9
substituting x=3 in f(x),
=> f(3)=9
The answer is 4 as 4x4 is 16 (squared means the number multiplied by itself) and
<em>16+16+9=41</em>
Therefore the answer is x=4
