F(x) = 2x + 1
f(3) = 2(3) + 1 = 6 + 1 = 7
g(x) = 3x + 2
g(2) = 3(2) + 2 = 6 + 2 = 8
f(3) ÷ g(2) = ⅞
Answer:
The square of a monomial is 
Step-by-step explanation:
Consider the provided monomial.

We need to Write the expression as a square of a monomial.
The above expression can be written as:



Hence, the square of a monomial is 
3 cm, there are 10 mm to a centimeter
Yes, the ordered pair (2,-4) is a solution to the equation.
2 = x
-4 = y
Subtitute x and y
-4=-2-2
-4=-4
Try this explanation:
1. if to simplify the equation into the form ax²+bx+c=0 then to calculate 'D' ⇒ x²-8x-20=0; D=16+20=36. The value of D is greater 0, it means the given equation has two solutions.
2. Wrong step and correct way are shown in the picture in the attachment.
3. Description of the solution: the points with x=1;3 are the intersection points of the function y=x²-4x+3 and Ox-axis.
PS. all the details are in the attachment.
