Remember: We have to work from either the LHS or the RHS.
(Left hand side or the Right hand side)
You should already know this:
You should also know this:
So plugging in both of those into our identity, we get:
Simplify the denominator on the LHS (Left Hand Side)
We get:
LHS = RHS
Therefore, identity is verified.
Answer:
6x - 12
Step-by-step explanation:
In this question, we area asked to write an expression for a mother’s age given some information about the children’s age. We proceed as follows:
Charlie is x years old and his sister is 4 years younger. His sister’s age would be x -4. The total of both ages would be their addition and that is x + x - 4 = 2x - 4
Now, the mother’s age is 3 times this quantity.
Mathematically, that is 3(2x -4) = 6x -12
The expression of the mother’s age is (6x-12) years
Answer:
First quadrant
Step-by-step explanation:
cosθ > 0 in first/ fourth quadrants
sinθ > 0 in the first/ second quadrants
sinθ and cosθ are both > 0 in the first quadrant
Then θ lies in the first quadrant
Answer:
3 is a right angle
Step-by-step explanation:
A false hypothesis helps to understand what factors are not related to a certain outcome. This helps center experiments around hypotheses that are more relevant.
