Clara is incorrect. When you do the math, 4 squared is basically saying multiply four times four. Which equals Sixteen. When you divide Sixteen by two you get eight, not four. My math is listed below.
4^2 (4 • 4) = 16
16/2 = 8
Hopefully this helped and good luck!!
I=P(1+(r/n))^nt
I is the value owed
r is the rate in a decimal
n is the times compounded (annually =1, quarterly =4, monthly =12 etc.)
t is time invested
I=8000(1+(.109/1))^5x1
I=8000(1.109)^5
I=8000(<span>1.67748)

to simplify it, we need to combine like terms. 8 and 15 are like, and 5x and 2x are like. so we rearrange it: 8+15-5x-2x
and now we simplify: 23-7x
Ok so first, let's combine the like terms on the right side by adding them
Now we look at them put back together
Now you have to move all your y's to one side and numbers without a variable to the other. So, for this we're going to add 6y to 7y on the right so the left side cancels out.
On the other side we subtract 6 from 19
and now to get the answer for y we divide 13 by 13 to get your answer of 1 :)
I would love to help! However I'm not sure what I'm supposed to be helping with. I could just be daft, but it isn't clear what you need from me.
