C.) because red is g and it goes up 6 right 6 an since blue is F it goes up 3 right 3 which would collide at the center

(f+g)(x) = x^2 -2x +6x + 4

(f+g)(x) = x^2 + 4x + 4

(f+g)(x) = (x + 2)^2

(x + 2)^2 = 0

x + 2 = 0

x = -2

answer

B. -2

68. 7 out of 8 students were surveyed to have their owned bike.
Now, let’s solve for the value of the number of students who owned a bike if the number of who does not owned is 72.
=> the ratio is 7 : 8
Now, the formula would be like this:
=> 7 : 8 = x : 72
=> First multiply the outer value
=> 7 * 72 = 504
=> Next, divide the product with the innerr value
=> 504 / 8 = 63
Thus, the value of the students who owned a bike is 63.

21x-9+6y

combining terms: 4x+17x=21x
