Answer:
-3(4+2n) multiply -3 by 4 and 2n
-12-6n
Answer:
5(-3) would be the first step
Step-by-step explanation:
5 * -3 = -15
-15 + 6 = -9
-9 is the answer
D - -x^2 + 3x + 7
To find this, first write out the equation:
(3x + 1) - (x^2 - 6)
Distribute the negative into x^2 and -6 so you're equation now looks like this:
3 x + 1 - x^2 + 6
Combine like terms and arrange the equation into ax^2 + bx + c to get the final answer of:
-x^2 + 3x + 7
Hope this helps!
