Which of the following is equivalent to (x+4)(3x^2+2x)?
Mrrafil [7]

We can multiple this binomial and this trinomial to find an equivalent expression.

(x + 4)(3x^2 + 2x)

3x^3 + 2x^2 + 12x^2 + 8x

Combine like terms.

3x^3 + 14x^2 + 8x is the equivalent polynomial.

Question 1:

7.488*10^{-8}÷3.12*10^{2}

= \frac{7.488*10^{-8}}{3.12*10^{2}} = 2.4* 10^{-8-2} = 2.4* 10^{-10}

Hence, the answer is A.

Question 2:

Mass = 2.8* 10^{-11} grams

New mass = 2.8 * 10^{-8} milligrams

Question 3:

2.085*10^{6} = 2,085,000
