We find the deferential by differentiating the function dy=(3x^2-3)dx
substituting the values for x and dx
dy=(3*2^2-3)(0.05)=0.45
We will start by expanding (or multiplying through) with 3(n+4)
We get:
3n + 12
3n can be expanded to equal 2n+n, so the correct answer will be
2n + 12 + n
Simply add the options together and see what one matches 3n + 12
2n + 12 + n = 3n + 12, which in turn equals 3(n+4)
ANSWER: 2n + 12 + n
The pattern is: x + x = x^2 + 2
So 6 + 6 = 36+2 = 38
B= -8
but if your looking for a two step equation it’s -2b-10=6
