Step-by-step explanation:
Answer:
The exponent 2 tells us that we must multiply 2 five's together.
So we have: 5^2 = 5 x 5
Let me know if this helps!
Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx
Step-by-step explanation:
Hmm I saw this question before its C
Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation
We need to solve for x. We have to isolate x here.
Here square on x. So, first we get rid of square.
Taking square root both sides to get rid of square.
For example:
a2=25
sqare a2 = +- sqare 25
x2=9/16 to solve for x
sqare x2 +- sqre 9725
x=+- 3/5
Hence, "Take the square root of both sides of the equation"
