To evaluate a function at a given input, you have to substitute every occurrence of the variable with that particular value.
So, for the first function, you have

The name of the variable is obviously irrelelvant, so the same goes for the second function:

Answer:

Step-by-step explanation:
16 divided by 6 is 2.66666667
Since 1/3 is .33 , 2/3 is .66
A cuz of how its functions
and D cuz of how it uses the numbers i guess
So.. if you notice the picture below
is really just 3/4 of a cylinder, or, a full cylinder, and then you slice 1/4 off of it
notice the right-angle in your picture at the bottom, is cut at a right-angle, meaning, the cutout is 1/4 of the volume
so
Question 10: P=28cm
if l=8 and w=6
Then (8+6)=14
2(14) so 14x2 = 28
So therefore P=28cm
