First you need to get rid of the parenthesis by multiplying everything thats in it by 2
so you get 2x - 6 + 4x + 3
now just add like terms
6x - 3
at this point theres nothing more you can do
your answer is B
i hope this helps !!
Answer:
85 cm
Step-by-step explanation:
the strut forms a right triangle with the end of the pole.
let the ends of the strut be x from the top of the pole . then
using Pythagoras' identity with 2 legs x and hypotenuse 1.2
x² + x² = 1.2²
2x² = 1.44 ( divide both sides by 2 )
x² = 0.72 ( take square root of both sides )
x = 
≈ 0.85 m ( to 2 dec. places )
the ends are 0.85 m = 85 cm from the top of the pole
For a triangle, the measure of the exterior angle is the sum of the angles that are non-adjacent to the exterior angle. If the given angles, L and J, are non-adjacent angles to the exterior angle at K, then the measure of the exterior angle is
45 + 65 = 110 degrees
If you cross multiply and the answers are the same.
2/5=4/10 because 5*4=20, and 10*2=20
