Problem: 2/7 (4+c)=6
1. 7/2 x 2/7 x (4+c)=7/2 x 6
2. 4+c=7 x 3
3. 4+c=21
4. c=21-4
Answer: c=17
If f(x) = {(2, 3), (4, 8), (7, –1)} and g(x) = {(8, 2), (–1, 4), (2, 7)}, find (f ◦ g)(x), if it exists.

Answer:
(f o g )(x) = {8, 3), (-1, 8), (2, -1)}
Step-by-step explanation:
(f o g)(x) = [f(g(x)]
g(8) = 2 and f(2) = 3
g(-1) = 4 and f(4) = 8
g(2) = 7 and f(7) = -1
So, (f o g )(x) = {8, 3), (-1, 8), (2, -1)}
Answer:
The length of all four sides of a quadrilateral are 7 inches, 14 inches, 10 inches, 10 inches
Step-by-step explanation:
Let the shortest side be 
As per given information longest side = 
and other 2 sides are equal in length but 3 more times that shortest side = 
Perimeter of Quadrilateral = 41 inches given
But perimeter of quadrilateral = sum of all sides

Shortest side = 
Longest side = 
Other 2 sides = 
Answer:
-5x²+13x+6
Step-by-step explanation:
(x-3)*(2x-7x-2)
(x-3)*(-5x-2)
-5x²-2x+15x+6
-5x²+13x+6
