Answer:
Multiply both sides of the equation
Step-by-step explanation:
Answer: surface area = area of BASE + 1/2 × perimeter of base × slant HEIGHT.
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:

First you need to get all variables on one side. You do that by multiplying the reciprocal of the fraction to everything.
N(5/1) x 1/5(5/1)=2/15(5/1)
5n=2/15 x 5/1
Then solve the multiplication problem
5n= 10/15
Then you should reduce the fraction
5n=2/3
Then divide both sides by 5
5n/5=N
2/3 divided by 5 =2/15
N=2/15
