If f(x)=4x^2-5x+7 and g(x)=3x^2-2x+8, find f(x) + g(x)

7x² - 7x + 15

Step-by-step explanation:

When we add two polynomial we add the co-efficient of the like terms. i.e., the coefficients of x², x and the constant term.

Given: f(x) = 4x² - 5x + 7

and     g(x) = 3x² - 2x + 8

f(x) + g(x) = 4x² - 5x + 7 + 3x² - 2x + 8

⇒ f(x) + g(x) = 7x² - 7x + 15

Hence, the answer.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
