Answer:
A. Dividing both sides by 4 isolates the variable.
Step-by-step explanation:
In order to solve for x, you need to get it all by itself. Dividing both sides of the equation by 4 gives you 8 on the right side and only x on the left side , therefore the variable is isolated. (This uses the Division Property of Equality.)
Yestheydo I am pretty sure
Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx
-1.7 - 2.3 x (-.15) / 0.1 + 2
= -1.7 + .345 / 0.1 + 2
= -1.7 + 3.45 + 2
= 3.75
Answer
d. 3.75
