The answer is that they are 1
If population in 2025 is 450 (in thousands)
15 years prior (2010, it is 450 - 15(4) or 390
now in years (p) after this date population increases 4 (in thousands) times the number of years.
<span>
<span>so formula would be p = 390 + 4p

Answer:
22u + 56
Step-by-step explanation:
-8(-10u + 6u - 7) - 10u
1.) Combine like terms
-8(-10u + 6u - 7) - 10u
-8(-4u - 7) - 10u
2.) Distribute
-8(-4u - 7) - 10u
-8(-4u) -8(-7) - 10u
32u + 56 - 10u
3.) Combine like terms
32u + 56 - 10u
22u + 56
Therefore, the simplified equation is 22u + 56.
Answer:
16x4+12x3−10x2+13x−3
Step-by-step explanation:
Let's simplify step-by-step.
16x4+12x3−10x2+8x+204x−3
=16x4+12x3+−10x2+8x+5x+−3
Combine Like Terms:
=16x4+12x3+−10x2+8x+5x+−3
=(16x4)+(12x3)+(−10x2)+(8x+5x)+(−3)
=16x4+12x3+−10x2+13x+−3
Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
