The question is somewhat ambiguous: the answers are LCM[3T2, 5T] =15T2 or LCM[(3T)2, 5T] =45T2
The answer to the math question Cos 5t cos 3t -square root 3 2 - sin 5t cos 3t equals 0. In order to find this answer you will have to find out what each letter is.
-3t
2t-5t=-3t
6t - 5t - 6 = (3t + 2)(2t - 3)
The GCF is t.
20t
7p+5t
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
3t - 1
5t + 1
-5t + 9 + 2t = 30Combine like terms on the left side:-3t + 9 = 30Multiply both sides by -1"3t - 9 = -30Add 9 to both sides:3t = -21Divide both sides by 3:t = -7
