i have answered ur question
Answer:
see explanation
Step-by-step explanation:
Consider the left side
A + 
A - 2cos²Asin²A ← is the expansion of
= (cos²A - sin²A)²
Substitute sin²A = 1 - cos²A
= (cos²A - (1 - cos²A) )²
= (cos²A - 1 + cos²A)²
= (2cos²A - 1 )²
= right side , then proven
X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)
Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390
Step 3: Divide both sides by 6
6x/6 = 390/6
