Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation
If I'm right, then the process is
Y=2(3)+1 (putting 3 in place of x)
Y=6+1
Y=7
Which makes 7 your answer

Answer:
70 is answer
Step-by-step explanation:
Given that a function in x is

we have to find f'(7)
we know by derivative rule derivative of a function is

For finding out at 7 we replace x by 7

=
So f'(7) = 70
answer is 70
Bottom Side Surface Area:
(24 inches + 24 inches + 24 inches) * (30 inches)
= 72 inches * 30 inches
= 2160 inches squared
--------
Top Side Surface Area:
24 inches * 30 inches
= 720 inches squared
--------
Length of the diagonal (D) which needs to be measured:
*Use Pythaogras's theorem...
24^2 + 10^2 = D^2
D=√(24^2+10^2)
D=26 inches
------------
Measure the surface area of the two ramps:
26 inches * 30 inches * 2
= 1560 inches squared
-----------
Total surface area:
2160 inches squared + 720 inches squared + 1560 inches squared
= 4440 inches squared
---------
Answer:
4440 square inches
