Write a polynomial function rule for g(x)+f(x) Consider the polynomial function
f(x)=7x^3+x2-4x+10
g(x)=c^2-5

Given:

Consider the given polynomials are:

To find:

The polynomial function rule for .

Solution:

We need to add both functions to get .

On combining like terms, we get

Therefore, the required function is .

y/x=18

step-by-step explanation:

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
