Cristiano Ronaldo has 45 fewer goals on record than Josef Bican. Write an expression to represent the number of goals Cristiano Ronaldo currently has if Josef Bican had G goals.

How many goals does Ronaldo have if Josef Bican has a record of 805 goals?

Correct A

Explanation:

A. Given that the equation x2+ mx+ n= 0 has two solutions, x = kand x = 2k,you can work backward to build the original equation. Here’s how:

x= kx= 2k

x– k= 0 x– 2k= 0

Now take the two equations and combine them:

(x– k)(x– 2k) = 0

x2– 2kx– kx + 2k2= 0

x2– 3kx + 2k2= 0

As you can see, m= –3kand n = 2k2, so mn= –6k3.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

283 square feet
