Answer:
A
Step-by-step explanation:
-19-11 = -19 + (-11)
First you have to simply distribute the + through the parentheses
16+f+4
Then you combine like terms (in this case the 16 and the 4)
f+20
16+(f+4) simplified is f+20
Hope this helps!!
It depends on the speed she was going?
Just use distributive property (multiply 7 times 7k and 7 times -10 )
This equals 49k-70
Hope this helped :)
