Answer:
True
Step-by-step explanation:
6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y
Regroup terms on left
6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y
Combine like terms
on left
12x² + 5x - 4y = 12x² + 5x - 4y True
Step-by-step explanation:
Consider LHS

Apply quotient identies

Multiply the fraction and sine.

Make cos x a fraction with cos x as it denominator.

so

Pythagorean Identity tells us sin squared and cos squared equals 1 so

Apply reciprocal identity.

Answer:
x = 61
Step-by-step explanation:
To answer this question, we combine like terms:
44 + 59 + 74 = 177
The total will have to be 360, so....
177 + x + x + x = 360
or
177 + 3x = 360
360 - 177 = 183
So, 3x = 183
183 / 3 = 61
So, x = 61!
