Hopefully this is the correct answer! but your expression would be: y=40x+30
and if he drove for 5hrs then you would plug in 5 for your x value so it would be y=40*5+30 and 40*5 is 200.(the star means multiplying) then add 30 to get a total of $230
so the expression is: y=40x+30
and if he drove for 5hrs then he sould make a total of: $230
hopefully that helped and was the right answer :)
Answer:
= 5x +35
Step-by-step explanation:
Steps
5(x+7)
Apply the distributive law: ab+c) = ab + ac
5(x+7) =5x + 5: 7
=5X+5: 7
Multiply the numbers: 5 7= 35
= 5x +35

i'd say with the given info it will be the same
Answer:
64z^2
Step-by-step explanation:
Here's why, it's actually very simple we use exponent rule when raising something to a power. In this case we're raising the term to the second power. So we raise both -8, and z. As so: (-8)^2 x (z)^2
Which equals 64z^2.
