We can check to see if (x - 2)(x - 9)(x - 1) is the factored form of x^3 + 8x^2 - 11x - 18 by using foil.
(x - 2)(x - 9)(x - 1)
(x - 2)x^2 - x - 9x + 9
Combine like terms.
(x - 2)x^2 - 10x + 9
FOIL again.
x^3 - 10x^2 + 9x - 2x^2 + 20x - 18
Combine like terms.
x^3 - 12x^2 + 29x - 18

Answer:
x=−9
Step-by-step explanation:
Let's solve your equation step-by-step.
x+5=2(7+x)
Step 1: Simplify both sides of the equation.
x+5=2(7+x)
x+5=(2)(7)+(2)(x)(Distribute)
x+5=14+2x
x+5=2x+14
Step 2: Subtract 2x from both sides.
x+5−2x=2x+14−2x
−x+5=14
Step 3: Subtract 5 from both sides.
−x+5−5=14−5
−x=9
Step 4: Divide both sides by -1.
−x
−1
=
9
−1
x=−9

Step-by-step explanation:
36 eggs in 3 cartons.
now we double the cartons, so, we need to double the eggs too, because there is a direct relationship between cartons and the number of eggs.
so. in 2×3 cartons are then 2×36 = 72 eggs.
If you want it to be 1/2 then you would have to color in another part, but if you want it to be 1/4 then that’s what you drew and you would have to change the denominator to a 4.
I hope this helped.
