Answer:
45
Step-by-step explanation:
using similar triangles
Let x be the boy's height
=
cross multiply to get 43.2x=1944
then divide by 43.2 both sides
to get x=45
Solution for the question asked: 3x^2-5x+4=6
it can be simplified by subtracting 6 from both the sides...
3x^2-5x+4-6=6-6
3x^2-5x-2=0 which is the required form where a=3,b=-5 and c=-2.Now putting the values in the formula we will get two values for x which are 6 and (-1).
hope this will help you
