f(x) = 4x + 3
g(x) = -2x + 5
(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115
Answer:
x = 4 + sqrt(5) or x = 4 - sqrt(5)
Step-by-step explanation:
Solve for x:
(x - 4)^2 = 5
Take the square root of both sides:
x - 4 = sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
x = 4 + sqrt(5) or x - 4 = -sqrt(5)
Add 4 to both sides:
Answer: x = 4 + sqrt(5) or x = 4 - sqrt(5)

B) no
c) D: (0, 128) domain is what are the possible numbers that can be put into a function. the reason it is 0 to 128 is because you cant have a negative number in this situation and 128 is the max because thats what you started out with
d) 4 teams
we know that having similar triangles so the ratio of sides,area and volume are same.
we know that 
will be the area of triangle.
so 
so the ratio of the perimeter of two triangles will be
ratio of the perimeter=
