3x(x+3)^2
3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x
answer
3x^3 + 18x^2 + 27x
Answer:
the correct answer is b
Step-by-step explanation:
Sure, you can either simplify it further: 1/2 and you could also multiply by 2: 4/8
40 below 0 would be -40 and 20 below 0 would be -20°. So there’s a change of (increase of) 20° that day. It would also make sense if you drew a number line. You would see the interval between -40 and -20 is 20.
1/8 because if u simplify your answer..to have 4 as the denominator it would work easier
