Which statement is true about 4 + 2x is true 1. 4+2x is a sum.
2. 4+2x is a product
3. there are 2 variables in 4+2x
4. the coefficient of x is 4

1. 4+2x is a sum

Step-by-step explanation:

In the expression

4 + 2x

there are two adding terms: 4 and 2x

the first term is a constant and the second term has only one variable (x)

the coefficient of x is 2

The analysis gives un only one correct choice:

1. 4+2x is a sum

9.462.5 ml

Step-by-step explanation:

1 liter = 1000 milliliters

1 gallon = 3,785 liters

To find how many milliliters has a gallon, simply multiply simple: 3,785 x 1000 = 3.785

Then 1 gallon has 3.785 ml

Then at 2.5 gallons we will have: 3.785 ml x 2,5 = 9.462.5 ml
