Answer:We are going to define the following variables:

A: Area of the original figure.

k: scale factor.

We have that the area of the new figure (reduced or enlarged, depends on the value of k) is:

A '= k ^ 2 * A

Example: rectangle of dimensions (2) * (3) A factor of k = 2 is extended. Find the new area.

The original area is:

A = (2) * (3) = 6

The new area will be:

A '= (2 * 2) * (2 * 3) = 4 * 6 = 24

Or equivalently:

A '= k ^ 2 * A

A '= (2) ^ 2 * (6) = 4 * 6 = 24

If f(x) = 3x^2 +1 and g(x) = 1-x, what is the value of (f-g)(2)
aleksley [76]

Answer:

14

Step-by-step explanation:

Let's find (f-g)(x)

3x^{2} + 1 - (1-x)\\3x^{2} + 1 -1 + x\\3x^{2} + x

Now let's plug in x=2, so to find (f-g)(2)

3(2)^{2} + 2\\12 + 2 = 14

aksik [14]
Hello!  I would be happy to help you with your math problem.  For this problem, we plug in the values until we find what fits.  In this case, we have to find what is true, or, in other words, equals 37.

The answer to your question would be B -- -3.  Here is why.

-15*-3-8=37.

Hope this helps!
