22000
The number that's being added in the sequence increases by 2x.
250 * 2 = 500, which is added to 18500 to equal 19000.
500 * 2 = 1000, which is added to 19000 to equal 20000.
1000 * 2 = 2000, which added to 20000 equals 22000.
The answer is 2.6. I could be wrong.
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.
Answer:
x^3+10x^2+31x+30
Step-by-step explanation:
(x + 5)(x +2) (x+3)
(x^2+7x+10) ( x + 3 )
=x^3+ 10x^2+ 31x +30
