X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.
Answer:
24
Step-by-step explanation:
If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.
So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
1500-125=1,375
so 1375 should be your answer.
The number of potential customers reached by the company is the total number of people that received their promotional material
First mailing list - 2,500 addresses
Second mailing list - 3,500 addresses
Third mailing list - 4,000 addresses
Total is, 2500 + 3500 + 4000
= 10,000
Therefore, their promotional materials reached 10,000 potential customers.
