<h2>(x + 4) (x + 4)</h2>
Step-by-step explanation:
= x² + 8x + 16
= x² + 4x + 4x + 16
= x (x + 4) + 4 (x + 4)
= (x + 4) (x + 4)

Answer:
2
Step-by-step explanation:
let the number be n, then
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
That is the number is 2
Answer:
Since this is a linear (non-exponential) population problem you can just use the standard y=mx+b form of an equation. Where m = (change in population/change in years)
The numbers you were provided state that over the course of 7 years (1998-1991) the population increased by 420 people (4130-3710). So, (420/7) = 60 = m. Assuming that the growth rate for 1990 is the same as 1991. then you would have a starting population of (3710-60) or 3650, that would be your "b" value since at t=0 P(t) = 3650. This yields a final equation of P(t) = 60t +3650. Check the answer at t=1 and you get the population during 1991: 3710.

Answer:
5d
Explanation:
5 is the coefficient and when put directly next to d gives you 5 times d
=x2+2xy+3xy+6y2
=x(x+2y) +3y(x+2y)
=(x+2y)(x+3y)
