Answer:

Step-by-step explanation:
We are given the function:

And we want to find F(<em>b</em> + 3).
We can substitute:

Expand:

Rearrange:

Combine like terms. Hence:

In conclusion:

Answer:
Neither
Step-by-step explanation:
If the sequence was geometric, each term would be multiplied by the same multiplier to get to the next one. We can check if the multiplier is the same by taking a term and dividing it by the term before it. For example,
-4/3.5=-1.14285714
-7.5/-4=1.87500
The multiplier between the terms aren't the same so it's not geometric.
For arithmetic, the distances between each term would be the same, and we can take the same idea from the geometric sequence, but use subtraction instead of division
-4-3,5=-7.5
-7.5-(-4)=-3.5
Again, the distances aren't the same, so it's not arithmetic.
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
