It is -11x + 24 because you multiply the numbers in the parentheses by 3 then collect like terms 10x +24 - 21x then you do 10x minus 24x and you get -11x+24
Answer: years of equal population are 1995 and 2022.
in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.
Step-by-step explanation: Baskinville: y = x2 - 22x + 350
Cryersport: y = 55x - 950
Note that x2 is xsquare not x2
Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

Answer:
900
Step-by-step explanation:
We assume that your 4-digit number must be in the range 1000 to 9999. Clearly, any number ending in zero will meet your requirement:
1000/100 = 10
3890/389 = 10
However, the requirement cannot be met when the 1s digit is other than zero.
__
For some 3-digit number N and some 1s digit x, the 4-digit number will be
4-digit number: 10N+x
Dividing this by N will give ...
(10N+x)/N = 10 remainder x
N will only be a factor of 10N+x when x=0.
So, there are 900 4-digit numbers that meet your requirement. They range from 1000 to 9990.
