Answer:
4 hours
Step-by-step explanation:
4 hours because if 15 is 3 hours. count by 5. 5 kilograms of dough would be 1 hour, 10 kilograms of dough would be 2 hours leaving 15 at 3 hours and 20 kilograms at 4 hours.
Answer:
See explanation
Step-by-step explanation:
An example of an equation with the distributive property would be:
3(x+4) = 30
The distributive property tells us:
3(x+4) = 3x+12, since the 3 carries into both x and 4.
Therefore, you have:
3x + 12 = 30
-> 3x = 18
-> x = 6
I hope this helps you
x= -1
g (-1)= -1+3=2
f (g (-1))=f (2)=?
x=2
f (2)=3.2^2+1
f (2)=3.4+1
f (2)=12+1
f (2)=13
