Step-by-step explanation:
here,
x^2 -3xy-18xy^2
=x^2-(6-3)xy-18xy^2
=x^2-6xy+3xy-18y^2
=x(x-6y)+3y(x-6y)
=(x-6y)(x-3y)
2.)82 degrees 4.)98 degrees
6.)123 degrees. 8.)60 degrees
Answer:
x = 73.4°
Step-by-step explanation:
sin x° = 23/24
sin x° = 0.9583
x = 73.4°
When we make a solution, the solute doesn't go away. All the solute we use stays in the solution it only dissolve in the solution.
The total mass of solution is always equal to the mass of solvent added to the mass of solute.
Therefore 5gram + 20 gram = 25 gram of solution.
5/25×100= 20%
It’s 1. (4x - 12 + 12 = 16 + 12)
