Step-by-step explanation:
The distributive property is as follows :
....(1)
We need to solve using distributive property
Applying property (1) on the LHS of given equation
Taking a = 24, b = d/4 and c = -5
So,
So, we get the value of d as 6 using distributive property.
Answer:
3xy
Step-by-step explanation:
You can only combine the like terms, i.e terms with the same variable)
xy is a product of 2 variables, unlike other terms listed (only in x)
Answer:
Step-by-step explanation:
(cos7A + cos3A - cos5A - cosA)÷(sin7A - sin3A - sin5a + sinA)
By using transformations,
[(cos7A - cos5A) + (cos3A - cosA)]÷[(sin7A - sin5A) - (sin3A - sinA)]....
we get...
=[(2sin6A.sinA)+(2sin2A.sinA)]÷[(2cos6A.sinA)-(2cos2A.sinA)]...
=[{2sinA(sin6A+sin2A)}]÷[{2sinA(cos6A-cos2A)]
=[{2sin4A.cos2A}÷{2sin4A.sin2A}]
=[(cos2A)÷(sin2A)]
=cot2A
