First. distribute and multiply the the 4 to the 3^2 and the -5
so then it becomes 21+ 36 - 20
second. add and subtract that
answer is: 37
The answer should be 1. Reflection over the x-axis and shifted 3 units to the left.
Here we use the formula for compound interest given by:
A=p(1+r/100*n)^(nt)
where:
A=amount=
p=principle=12000
r=rate=0.1
n=# terms=2
t=time=10 years
thus;
A=12000(1+0.1/2)^(2*10)
A=31839.6
