Find f(2) for f(x)=3x2+9x−6
Naya [18.7K]

Answer:

a. f(2)=24  

Step-by-step explanation:

Given function:

f(x)=3x^2+9x-6

To find f(2)

Solution:

In order to find f(2),we need to plugin input=2 i.e. the value of x=2 in the function and find the output by evaluating.

Plugging in x=2 in the given function.

f(2)=3(2)^2+9(2)-6

Evaluating.

f(2)=3(4)+18-6

f(2)=12+18-6

∴ f(2)=24   (Answer)

A field is a rectangle with a perimeter of 1240 feet. The length is 400 feet more than the width. Find the width and length of t
Wewaii [24]

Answer:  The length is 510 and the width is 110.

Step-by-step explanation:

To find the area of a rectangle, you will have to add the 2 times the length plus 2 times the width because  a rectangle have 4 sides. Two widths and two  lengths.

You can now use the formula  P= 2l + 2w  

were P is the perimeter , l is the length, and w is the width.

the length is 400 more than the width, so we can represent that by the equation,  l = w + 400  

And now we know that the width is w.

So now we will input the perimeter, length, and into the formula to solve for w.

1240 = 2(w + 400) + 2w

1240 = 2w + 800 + 2w

1240 = 4w + 800

-800            -800

   440 = 4w

    w = 110

L= 110 + 400

L = 510  

Check :

1240 = 2(510) + 2(110)

1240 = 1020 + 220

1240 = 1240
