Answer:
17+3/4
Step-by-step explanation:
<h3><u>The value of the first number, x, is eual to 2.</u></h3><h3><u>The value of the second number, y, is equal to -1.</u></h3><h3><u>The value of the third number, z, is equal to 8.</u></h3>
x + y + z = 9
y = x - 3
z = 2x + 4
Because we have values for y and z, we can find the exact value of x, which we can use to find the exact values for the other variables.
x + x - 3 + 2x + 4 = 9
<em><u>Combine like terms.</u></em>
4x + 1 = 9
<em><u>Subtract 1 from both sides.</u></em>
4x = 8
<em><u>Divide both sides by 4.</u></em>
x = 2
Now that we have a value for x, we can plug this value in to each other x value to solve for y and z.
y = 2 - 3
y = -1
z = 2(2) + 4
z = 8
2,242
Because if there are 59 rows of seats in that section and 38 seats in each row you would do 59x38

Answer:
x^3+2x^2-x-2=(x+2)(x-1)(x+1)
The other two factors are x-1 and x+1
Step-by-step explanation:
Use synthetic division:
x^3+2x^2-x-2 / x+2
-2 | 1 2 -1 -2
-2 0 2
_________
1 0 -1 0
This means x^2-1 with no remainder, but we can still break it down. The factors of -1 are 1 and -1, so we must find the factors:
1 | 1 0 -1
1 1
______
1 1 0
This means x+1 so that's one factor
-1 | 1 0 -1
-1 1
_______
1 -1 0
This means x-1 so that's the other factor
Thus, the factors of x^3+2x^2-x-2 are (x+2)(x+1)(x-1)
