Answer:
39
Step-by-step explanation:
f(x)=17x
f(3)=17(3)
f(x)=51
g(x)=4x
g(3)=4(3)
g(x)=12
f(x)-g(x)
51-12= 39
Answer:
3
Step-by-step explanation: y=10-x so 3x-2=10-x 4x=12 x=3
Answer: 4 radical 10
Reason:
First you have to add 3 radical 2 and radical 2, getting 4 radical 2.
Then you multiple 4 radical 2 by 2 radical 5 and you get 8 radical 10.
Then you divide that by 2 to get the area of a triangle so then it comes back to 4 radical 10
