Answer:

r = -3

Step-by-step explanation:

Simplifying

5r + 15 = 0

Reorder the terms:

15 + 5r = 0

Solving

15 + 5r = 0

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5r = 0 + -15

Combine like terms: 15 + -15 = 0

0 + 5r = 0 + -15

5r = 0 + -15

Combine like terms: 0 + -15 = -15

5r = -15

Divide each side by '5'.

r = -3

Simplifying

r = -3

What is 4(3+x) and how do I solve it
anastassius [24]

Answer:

12 + 4x

Step-by-step explanation:

To solve this you would have to use the distributive property.

The problem would basically go like this.

4 (3+x)

(Distribute)

(4x3) (4 x X)

4x3 = 12, 4 x x = 4x

So the answer would be 12 +4x

Hope this helps :)

Which factoring method would be best to factor x^2 - 9?
Vinil7 [7]

Answer:

  D.  difference of squares

Step-by-step explanation:

Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.

  a^2 -b^2 = (a -b)(a +b)

  x^2 -9 = (x -3)(x +3)
