Answer: Choice A) 12x^2 - 48x + 21; all real numbers
===========================================================
Work Shown:
(f * g)(x) = f(x) * g(x)
(f * g)(x) = ( f(x) ) * ( g(x) )
(f * g)(x) = ( -2x+7 ) * ( -6x+3 )
(f * g)(x) = -2x*( -6x+3 ) + 7*( -6x+3 )
(f * g)(x) = -2x*(-6x) - 2x*(3) + 7*(-6x) + 7*(3)
(f * g)(x) = 12x^2 - 6x - 42x + 21
(f * g)(x) = 12x^2 - 48x + 21
The domain is the set of all real numbers because we can plug in any number in for x, to get some output for y. There are no issues to worry about such as division by zero errors, square root of a negative number, etc.

Answer:
The actual space shuttle is 66 feet tall
Step-by-step explanation:
scale of 1 inch : 12 feet represent the scale of a space shuttle.
It means it has a representation of 1 inch on paper then actual = 12 feet.
But then if the paper(model) changes to 5.5 inches. The actual representation on land will be
Let me write out the equation
1 inch = 12 feet
5.5 inch =( 5.5 inch *12 feet)/1 inch
5.5 Inch= 5.5 * 12 feet
5.5 inch = 66 feet
The answer would be the second option B) because we can cross out A) and D) since those are multiplication, and it's not C) because that's commutative property, not associative.
