Solve cos²t + cos2t + 1=0. Statements:
1. The equation 3cos²t = 0 may be used to solve the equation.
2. The equation cos²t + 2cost + 1 = 0 may be used to solve the equation.
3. t = π/2 + πk, where k = 0, ±1, ±2, ±3.
4. t = π + 2πk, where k = 0, ±1, ±2, ±3.
a. 1 & 3 only.
b. 2 & 4 only.
c. 2 & 3 & 4 only
d. All statements are correct.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it

it would open into a square depending on the type of envelope i’m not sure about the second part

are ya tryin to ask something or is this a statement
