First step is simplifying both sides of the equation.
-8 + (3)(9y) = 8 -9 -7y +299
-8 +27y= -7y +(8 -9 +299)
Then, combine like terms.
-8 +27y = -7y +298
Add 7y to both sides which turns 27y to 34y and gets rid of the 7y on the right side.
-8 +34y = 298
Add 8 to both sides.
34y = 306
Divide both sides by 34.
34y/34 = 306/34

Which expression is equivalent to sin(1.8x) sin(0.5x)?
Rasek [7]
Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!

What is the sum of 2x+x+2x+x
Law Incorporation [45]
You’ll need to combine like terms to solve. All terms are x here, so we simply add all coefficients. 2 + 1 + 2 + 1 = 6, so the sum will be 6x.
