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

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
