Answer:
- 32.2
- -32.61
Step-by-step explanation:
The addition property of equality is used when we add 9 to both sides
6x-9 = 45
6x-9+9 = 45+9
6x = 54
The next step would be to divide both sides by 6 using the division property of equality
6x = 54
6x/6 = 54/6
x = 9

Answer:
21/4
Step-by-step explanation:
3sin²60 + cot²30
sin 60 = √3/2
cot 30 = √3
Substituting values in equation,
3(√3/2)² + (√3)²
=> 3(3/4) + 3
=> 9/4 + 3
=> 9/4 + 12/4
=> 21/4
