Answer:
The answer is 22 3/4
Step-by-step explanation:
So what i did was multiply 3 1/2 and 6 1/2.
And got 22 3/4!
12.25 inches. the equation to find that would be 3.5 squared or 3.5 times 3.5

Step-by-step explanation:
Answer:
6th period.
Step-by-step explanation:
Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
