What is the product?<br><br> 2x(x – 4)
sashaice [31]

Keywords:

<em>Product, factors, polynomial, distributive property </em>

For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: a (b + c) = ab + ac.

So:

2x (x - 4) = 2x * x-2x * 4\\2x (x - 4) = 2x ^ 2-8x

Thus, the product of 2x (x - 4) is: 2x ^ 2-8x

Answer:

The product of 2x (x - 4) is: 2x ^ 2-8x

A baseball team played 25 games and won 10 of them. What percent of the games did they win?
GalinKa [24]

Answer: 40%

Step-by-step explanation:

Setting up an equation to solve,

25 as the denominator representing the total number of baseball games played to represent the "whole."

10 as the numerator representing the number of games the baseball games won to represent the "part" you want to calculate as a percentage.

The equation, looking like this,

10/25 = ___

after calculating the equation you get 2/5 as reduced, evaluating that in terms of percentage you get 40% as 5 represents 100% (the whole) and 2 representing 40% (the number of baseball games won)
