They are not like terms because like terms must have the same variables. 8x^2y and -5xy^2 do not have the same variables. If the question was 8x^2y and -5xy^2 then it would be like terms.
You can use cubes to help you write an expression and model the problem by using the cubes in replace of numbers. It should be a lot easier. Then after you finish you just have to write it down. There are other ways, but this is just one.
3(x-2)>-3
x-2>-1
x>-1+2
x>1
Hope my answer helped u :)
Answer: the expression is
A = Sin^-1(D/bc)
Step-by-step explanation:
The formula for determining the area of a triangle is expressed as
Area = bcSinA
Where b and c are the length of each side of the triangle. Angle A is the given angle corresponding to side a.
The area of the given triangle is D. It means that
D = bcSinA
Therefore, the expression that can be used to find the measure of angle A would be
D = bcSinA
Dividing both sides of the equation by bc, it becomes
D/bc = bcSinA/bc
SinA = D/bc
Taking inverse of sine of both sides of the equation, it becomes
A = Sin^-1(D/bc)
