Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
Answer:

Answer:
Use Sin if Opposite Hypotenuse, Use Cosine if Adjacent Hypotenuse, and Use Tangent if Opposite Adjacent
Answer:
1/4y
Step-by-step explanation:
(-x^-1)^0/(4y^-1*y^2)
anything to the power of 0 gives you 1,
1/(4y^-1*y^2)
-1+2=1
1/4y^1=1/4y
