Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
Subtract 7 from both sides of the equation
Simplify
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.
Answer:
1. 15-5x 2. 54+18x 3. 3x+15 4. 28x+56
Step-by-step explanation:
I dont get if you need this or the real answer if you need the real answer let me know and I will give you the real answer. :) Have a good day!
We are asked to solve the equation 2x³ - 32x = 0. First off, we can see that the variable x appears in both terms on the left-hand side of the equation. Therefore, we can factor it out. We can also factor out a common factor of 2 from both terms.
2x³ - 32x = 0
2x(x² - 16) = 0
We can use the difference of squares pattern to further simplify the equation.
2x(x + 4)(x - 4) = 0
Now, using the Zero Product Property, set each term to zero.
2x = 0
x = 0
x + 4 = 0
x = -4
x - 4 = 0
x = 4
Therefore, the solutions to the equation 2x³ - 32x are 0, -4, and 4. Hope this helped and have a great day!
