we are given

Firstly , we can distribute tan^2 inside
we get

now, we can simplify it

we know that
tan=1/cot
so, tan^2 will get cancelled with cot^2

so, option-C..............Answer
Well, let's write it out, shall we?
6c2-5d+8
Now plug in the numbers.
6(5^2)2-5(4)+8
Now simplify using PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition and Subtraction (They go together go from left to right in the equation)
5^2= 5*5 = 25
6 * 25 = 150
150 * 2 = 300
5 * 4 = 20
Rewrite the equation.
150-20+8
Use PEMDAS again ( refer to the previous mentioning)
150 - 20 = 130
130 + 8 = 138
Answer:
C
Step-by-step explanation:
The function multiplies by 8 so 6 would be 48 and 10 would be 80.
Have a great day!
