Answers

1. sqrt 8 = 2.8
sqrt 72 = 8.5
There are 6 positive integers between these numbers (3 to 8).

2. So the 65th odd number is 2 * 65 – 1 = 129.

Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.

4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )

= 4 ( x(x+6) -3 (x + 6)

= 4 ( x + 6 ) ( x - 3 )

Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

Answer:

Answer:

4(x-3)(x+6)

Step-by-step explanation:

We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.

Then we factor this to get (x-3)(x+6).

So the factored form of the equation is 4(x-3)(x+6)
