Answer:
Whats the problem? and what class (algebra...)
Step-by-step explanation:
This is simple multiplication
do 2*4 and 10*4
so you get f(x)=8 and x=40
if you wanna do it by doing division do
2=10
f(x)=40
cross multiply then divide
so do 2*40 to get 80
then do 80/10 to get 8
60 = 2 x 30
30 = 2 x 15
2 = 2
15 = 3 x 5
Prime factors = 2 x 2 x 3 x 5 = 60.
Hope this helps
1.50*12 = $18
18 < 1800 so that is not true, she made a mistake.
