the answer is B. 72 mm^2 because
9x4.5=40.5
then
7x4.5=31.5
then
40.5+31.5=72.0 mm^2

Answer:
6
Step-by-step explanation:
3z = 18
Divide boboth sides by 3
3z/3 = 18/3
z = 6
<span>Combine the logarithms first: log5(4x+3)-log5(x-1). Since it's subtract, divide the two.
log5((4x+3)/(x-1))=2
Make both sides the exponent of five. 5^log5 cancels out.
5^(log5(4x+3/x-1))=5^2
4x+3/x-1=25
Multiply both sides by (x-1) to get rid of it under 4x+3.
(x-1)4x+3/x-1=25(x-1)
4x+3=25x-25
Now subtract 4x from both sides AND add 25 to both sides. This way you'll have all the x's by itself.
28=21x
Divide both sides by 21.
28/21=x
x=1.33333333333...

Answer:
There were 120 events planned.
Step-by-step explanation:
We are given the following information in the question:
f(x) represents the total monthly expenses for planning x events.
Cost of expenses for the company at the end of one month = $12,350
We have to find the number of events planned that is we have to find the value of x.
Thus, there were 120 events planned.
