Answer:

9

Step-by-step explanation:

15x^2 + 2x + 9

A constant does not have a variable with it

15x^2 is the quadratic term

2x is the linear term

9 is a constant term

Anna [14]
You would add the x to both sides, cancelling out the x on the side with 2y. Then you divide by 2 leaving you with y=1/2x+3

Use law of sines or law of cosines to find the length of side AB Please show work !!
scoray [572]

Answer:

AB = 11.3

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}

So, we have:

\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}

Make AB the subject

AB = \frac{15}{\sin(70)} * \sin(45)

AB = \frac{15}{0.9397} *0.7071

AB = 11.3
