Answer:

$=-2nm^2+2nm+6n$

Step-by-step explanation:

$-2n\left(m^2-m-3\right)\\\mathrm{Distribute\:parentheses}\\=\left(-2n\right)m^2+\left(-2n\right)\left(-m\right)+\left(-2n\right)\left(-3\right)\\Apply\:minus-plus\:rules\\+\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab\\=-2nm^2+2nm+2\cdot \:3n\\\mathrm{Multiply\:the\:numbers:}\:2\cdot \:3=6\\=-2nm^2+2nm+6n\\$

Answer:

Step-by-step explanation:

We will first find the prime factorization of 32 and 39. After we will calculate the factors of 32 and 39 and find the biggest common factor number .

32=2^5

39=3^1*13^1

List of positive integer factors of 32 that divides 32 without a remainder.

1,2,4,8,16

List of positive integer factors of 39 that divides 32 without a remainder.

1,3,13

We found the factors and prime factorization of 32 and 39. The biggest common factor number is the GCF number.

So the greatest common factor 32 and 39 is 1.

The two top NBA players played a basketball game against the RSM team. Together the NBA players made 85 baskets, scoring one poi

Afina-wow [57]

Answer: 36 three-point field goals.

Step-by-step explanation:

To solve this problem, set up a system of equations. Let's call the number of one-pointers $w$ , the number of two-pointers $x$ , and the number of three-pointers $y$ . We are trying to find $y$ here. We also know that $w+x+y=85$ , because that is the total amount of baskets, and also that $w+2x+3y=184$ , which is the total amount of points. We know that there were 22 free throws, so that means we can take away 22 baskets from the first equation, and also 22 points from the second equation. Now the equations are $x+y=63$ and $2x+3y=184$ . Solving the equations using our knowledge of systems of equations, you get that $y=36$ . So, 36 is the answer. Let me know if anything was unclear, and I hope this helped.
