What do you mean sin squared times x?
sin ^2 x means one and only one thing, (sin x) ^2
same as sin ^ n x = (sin x) ^n and cos ^n x = (cos x)^n
you need to know (and why):
sin ^2 x + cos ^2 x = 1
cos 2x = 1 - 2sin ^2 x (= cos ^2 x - sin ^2 x)
so sin ^2 x + cos (2x) - cos x = sin ^2 x + 1 - 2 sin ^2 x - cos x = 1 - sin ^2 x - cos x = cos ^2 x - cos x = cos x(cos x - 1)
4x times 4x equals 16x2.
We know that when you submit questions you aren't free to use the right format to make the mathematical terms crystal clear. It is likely that you mean "x squared times 6 plus x squared times 2", which is clearer. You can factor out the "x squared" and you will see that you get "x squared times 8". You COULD mean (6x) squared plus (2x) squared, which would be different. 6x times 6x would equal x squared times 36, so your answer will be much different.
Since area equals Pi times radius squared take and substitute what is known. 345 equals Pi times the radius squared. divide Pi into both sides for 109.8 equals the radius squared. Now take the square root of 109.8 to get an r of 10.47936 cm.
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).
4 squared is 16. 4 squared means that 4 is used as a factor 2 times. 4x4=16
It is cos2x that is, "cos-squared x".
4x times 4x equals 16x2.
The GCF of 84 and 144 is 12. You must do the prime factorization of each number. The prime factorization of 144 is 2 to the fourth power times 3 squared. The prime factorization of 84 is 2 squared times 7 times 3. You take the least of each common factor which would be 2 squared and 3. Two squared equals 4 and 4 times 3 equals 12, so the GCF is 12.
Energy equals mass times the speed of light squared.
46 squared or times itself equals 2116.

2 times 13 = 26 26 also = 1 squared + 5 squared
Yes, x times x equals x squared.
0 squared is 0. Zero times zero equals zero.

base squared times height squared equals the hypotenuse squared. then you know the hypotenuse.
