The question is related to trigonometry and we have to use the formula of double angle .
Here we use double angle formula of tangent function which is
Given expression is
Comparing it with double angle formula, we will get x = 5
SO the required expression is equal to
So the answer is tan(10) .
Answer:
The 2 Option Is Correct
f(x) = 2(x+3)(x-7)
Step-by-Step Explanation:
Factor.
1.) 20 miles for his round trip each day
Answer:
x = 13 1/2 or 27/2
Step-by-step explanation:
1st Add 2 to both sides: 2/3x-2+2=7+2
2nd Simplify: 2/3x = 9
3rd Multiply both sides by 3: 3*2/3x=9*3
4th Simplify: 2x=27
5th Divide both sides by 2: 2x÷2=27÷2
6th Simplify: x = 13 1/2 or 27/2
Answer:
A
Step-by-step explanation:
A: The student incorrectly divided both sides by 35. The student should first add 10 to both sides, obtaining 35x = 15, and then divide 15 by 35, obtaining the final answer 3/7.
