Answer:
30 feet
Step-by-step explanation:
For this problem we can use ratios 6:4 and x:20. We can also write these ratios as fractions 6/4 and x/20 or 3/2 and x/20. Set the two fractions equal to each other and solve for x:
3/2 = x/20
1.5 = x/20
30 = x

.
x = -1
7x-3x = -8+4
4x = -4
4x/4 = -4/4
f(g(x) ) = -2(3x²+5x+14) +10
= -3x²-10x- 28+10
= -3x²-10x -18
