F(x) = 3(x + 5)2 - 10

f(x)=3x2+30x+65

Step-by-step explanation:

F(x)=3(x+5)2-10

Using bodmas

B= bracket

O=of

D= division

M= multiplication

A= Addition

S= subtraction

So we go with the bracket

(X+5)2

=(x+5)(x+5)

Open the bracket

=x2+5x+5x+25

=x2+10x+15

Substitute for (x+5)2

F(x)=3(x2+10x+25)-10

Open the bracket

F(x)= 3x2+30x+75-10

F(x)= 3x2+30x+65

28 of the  foot pieces can be cut from the 50 foot piece.

Given the following data;

In this exercise, you're required how many   foot pieces can be cut from the 50 foot piece. To do this we would divide the 50 foot piece of PVC pipe by .

÷ =

Simplifying the equation, we have;

Number of pipes = 27.77 ≈ 28 pipes.

Therefore, 28 of the   foot pieces can be cut from the 50 foot piece.
