It would become 4.3 because 6 is 5 or greater so you round up.
Use the distributive property
10-6-4x=0
4-4x=0
All correct except that

The answer is D, Multiplication
Although there i no triangle given as the question requires, I am still going to answer because I understand it.
ABC is a right angled triangle. The triangle is 90° at C.
The trigonometric ratio sine is given by, sine = opposite/hypotenuse .
Cosine = adjacent/hypotenuse
So therefore, Sin A = 24/30
= 4/5
Cos A = 18/30
= 3/5
