Answer:
2 is -1/3
3 is -6
4 is 2
Step-by-step explanation:
2 is 7x + 8x = 3x - 4
3 is 5x + (-3) = 2x + (-15)
4 is -4x + 17 = 6x -3
No, she multiplied the exponents instead of adding them.
We can use the distributive property to simplify this expression.
I split this up into different parts--it helps me visualize better.
To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"
Then, "5(-2m + 2n)" becomes "-10m + 10n"
Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"
We can then simplify even further by combining like terms. The final expression is: C
Hope this helps!
