Answer: C) Find the factors of c that add up to b.

==============================================

Explanation:

If we want to factor something in the form x^2+bx+c, then we look for two numbers that

Multiply to c
Add to b

-------------

Let's look at a specific example

Consider factoring x^2+5x+6

We need to find two numbers that...

Multiply to c = 6
Add to b = 5

Through trial and error, you should find the two numbers to be 3 and 2. This means it factors to (x+3)(x+2). The order of the factors doesn't matter.

You can use the FOIL rule or the box method to expand out (x+3)(x+2). You should get x^2+5x+6 again.

Zielflug [23.3K]

Answer:

The coordinates of B' are (-3, 5).

Step-by-step explanation:

For every 90 degrees rotated, the coordinate numbers switch and one is multiplied by -1, when clockwise it's the 2nd one, and when counterclockwise, it's the 1st.

Adults be x
Campers be y

Total rooms =200

So inequality is given by

$\\ \sf\longmapsto x+y\leqslant 200$

Now

Adult costs 4$ and Camper costs 3\$

Inequality is given by

$\\ \sf\longmapsto 4x+3y\leqslant 750$
