What is the sum of the coefficients of the expression 3x^4+5x^2+x?

The sum of coefficients = 9

Step-by-step explanation:

The given expression is,

3x⁴ + 5x² + x

There are three terms in the given expression. All the terms contains variable x.

To find the coefficients of each terms

term        coefficients

3x⁴            3

5x²            5

x               1

To find the sum of coefficients

sum = 3 + 5 + 1 = 9

Therefore the sum of coefficients = 9

The answer is: 9

To find the sum of the coefficients of the polynomial we have, we need to evaluate

So,

The sum of the coefficientes of the expression is 9

Have a nice day!

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

pretty sure 750 each month!
