What is the flat rate for shipping? it would be 13n and then + or - the number given (flat rate for shipping)
hope this helped :)
To find the area of a triangle, the formula is

=A
Since you have the area and the base you can replace the variables and place the numbers into its place.
17.5 =

From here you need to solve for h by first multiplying the (1/2) and 7 which would equal 7/2 or 3.5
Then you would have
17.5 = 3.5(h)
Now you divide both sides by 3.5 which would make h equal to
h=5
Double check and do

which would equal to

All of that equals to 17.5, which is the correct answer so the height is 5m.
The answer for this question is d

You used distributive property because when there’s parentheses in a equation you need to distribute the number outside of the parentheses
Answer:
Step-by-step explanation
I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.
f(1) = 3
f(3) = -1
f(-1) = 7
But there is a minus in front of the left most f. That would make it - 7
