Answer:
A, C
Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True
Double angle 
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula 
D) False No further development towards a Trig Identity

Answer:
31 tacos
Step-by-step explanation:
(let t be the number of tacos last Tuesday)
178=23+5t
178-23
155=5t
155÷5
31=t
Log[6] * 4x2 + -1log[6] * x = 2
Reorder the terms for easier multiplication:
6 * 4glo * x2 + -1log[6] * x = 2
Multiply 6 * 4
24glo * x2 + -1log[6] * x = 2
Multiply glo * x2
24glox2 + -1log[6] * x = 2
Reorder the terms for easier multiplication:
24glox2 + -1 * 6glo * x = 2
Multiply -1 * 6
24glox2 + -6glo * x = 2
Multiply glo * x
24glox2 + -6glox = 2
Reorder the terms:
-6glox + 24glox2 = 2
Solving
-6glox + 24glox2 = 2
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Reorder the terms:
-2 + -6glox + 24glox2 = 2 + -2
Combine like terms: 2 + -2 = 0
-2 + -6glox + 24glox2 = 0
Factor out the Greatest Common Factor (GCF), '2'.
2(-1 + -3glox + 12glox2) = 0
Ignore the factor 2.
Subproblem 1
Set the factor '(-1 + -3glox + 12glox2)' equal to zero and attempt to solve:
Simplifying
-1 + -3glox + 12glox2 = 0
Solving
-1 + -3glox + 12glox2 = 0
Move all terms containing g to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + -3glox + 1 + 12glox2 = 0 + 1
Reorder the terms:
-1 + 1 + -3glox + 12glox2 = 0 + 1
Combine like terms: -1 + 1 = 0
0 + -3glox + 12glox2 = 0 + 1
-3glox + 12glox2 = 0 + 1
Combine like terms: 0 + 1 = 1
-3glox + 12glox2 = 1
