Answer:

Step-by-step explanation:

x=-2, x=3

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

x^2+5x+6=(-2)^2+5(-2)+6=(-2)(-2)-10+6=4-10+6=-6+6=0

x^2+5x+6=3^2+5(3)+6=9+15+6=24+6=30

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

x^2-x-6=(-2)^2-(-2)-6=4+2-6=6-6=0

x^2-x-6=3^2-3-6=9-3-6=6-6=0

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

Martiza remembers her pin because it is between 1000 and 1500 and it is a product of two consecutive prime numbers what is her p
Anna71 [15]

Answer:

Her pin must be 1147

Step-by-step explanation:

A little trick I have up my sleeve when I have these kind of questions is that I find the square root of each number, then find what is prime.

\sqrt{1000}  = 31.6

\sqrt{1500} = 38.7

Since the only prime numbers in the range of 31 and 38 is 31 and 37.

We can then multiply 31 by 37 to get 1147.
