Answer: -2x^6+x^5-x^3-2+2x^2 Hope that helps!

Step-by-step explanation:

1. Remove Parentheses x^6-2x^5-x^3-7-3x^6+3x^5+2x^2+5

2. Collect like terms (x^6-3x^6)+(-2x^5+3x^5)-x^3+(-7+5)+2x^2

3. Simplify and your answer would be -2x^6+x^5-x^3-2+2x^2

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Je

The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method

The given equation is $\frac{x}{3} + 8 = -2$

Solving the equation using Natasha's method

the fist step is to multiply by 2

x + 24 = - 6

The second step is to combine and add similar terms

x = -24 - 6

x = -30

Second method of solving the equation

The equation the friends are trying to solve is $\frac{x}{3} + 8 = -2$

The first step is to combine similar terms

$\frac{x}{3}$ = - 8 - 2

The second step is to add similar terms together

$\frac{x}{3}$ = - 10

The third step is to multiply both sides of the equation by 3

x = (-10 x 3)

x = -30

B -23 because adding two negatives keeps the negative on. So add the numbers like positives and then re-add the negative back on
