Answer:
Step-by-step explanation:
We are given the equation 
. To solve this equation, we can divide both sides by 2 to get that 
.
Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)
x = 3
Answer:
2(x + 3)(x + 1)(x - 4)
or 2x^3 - 26x - 24.
Step-by-step explanation:
We can write the polynomial if factor form:
P(x) = a(x + 3)(x + 1)(x - 4) where a is some constant.
Now, since f(-2) = 12 we can write :
12 = a(-2 + 3)(-2 + 1)(-2-4)
12 = 6a
a = 2.
So the polynomial is
2(x + 3)(x + 1)(x - 4).
Expanded that is
2(x + 3)(x^2 - 3x - 4)
= 2(x^3 - 3x^2 - 4x + 3x^2 - 9x - 12)
= 2x^3 - 26x - 24.
1. Add a positive integer by moving to the right on the number line.
2. Add a negative integer by moving to the left on the number line.
3. Subtract an integer by adding its opposite.
The answer is only 5/8 slices of cake is left. Hoped this helped!
