If n + 7 = 10, evaluate 2n - 2<br> O 3<br> 0 17<br> 4<br> 6

Alexandra [31]

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

$n + 7 = 10$

Subtract 7 from both sides of the equation

$n+7-7=10-7$

Simplify

$n=3$

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

= 6 - 2

= 4

Therefore, the value of 2n - 2 is 4.

Add (3x4−2x3+4x−2) and (3x3−2x2−x+4). Question 2 options:

Natalka [10]

Answer: 3x^4 +x^3 -2x^2 +3x +2

Step-by-step explanation:

(3x^4 - 2x^3 + 4x -2) + (3x^3 - 2x^2 - x +4)

There are no like terms for 3x^4, so leave it alone.

-2x^3 + 3x^3 = 1x^3

No like terms for -2x^2

4x - x = 3x

-2 + 4 = 2

Answer? 3x^4 +x^3 -2x^2 +3x +2
