think about it, its equal to the original price minus 15%
The area of lens is 3.14 square yards.
Step-by-step explanation:
Given,
Circumference of lens = 6.28 yards
Circumference = 2πr

Dividing both sides by 6.28

Area of lens = πr²
Area of lens = 
Area of lens = 3.14 square yards
The area of lens is 3.14 square yards.

Well since we know the roots are x = 5 and x = -1/4. We can convert it into an equation and make it equal to 0.
Simply work backwards instead of solving for x. For x = 5, it would be x - 5 = 0, because if you solve for x it will be 5.
Same thing for x = -1/4, the equation would be x + 1/4 = 0.
(X-5)(x+1/4) = 0.
Now multiply the 2 binomials together to get the quadratic. To get rid of the fraction after obtaining the quadratic multiply by 4 for each term in the quadratic.
F(-3)= 3(-3^2)
=3*9=27
therefore, g(f(-3))= 3-2(27)
