For part a you need to factor. X to the power of 2 is 2x. when you add it its turns into 2x+10x+16=0

2x+10x=12x

12x+16 will be your final answer

To factorise you have to find what multiplies to the number without an x and adds to the number with x
What times to 16 and add to 10?
8 and 2
Put these in brackets with x
(x+8)(x+2)=0
To find what x is you need to make both bracket equal zero
The easy way to do this is to flip the sign
x=-8
x=-2
The solutions represent the roots of the graph which is when it crosses the x-axis. The two solutions represent what x would equal when y=0 in this equation.

This one is the Law of Sines again.


The Law of Sines relies on the standard labeling of triangle ABC with vertices A, B, and C and respective opposite sides of a, b and c. Then


\dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C}


Here we have A=150 degrees (opposite side a), b= 10 cm and B = 12 degrees. We seek a.


So we need the first equation of the Law of Sines:


\dfrac{a}{\sin A} = \dfrac{b}{\sin B}


a = \dfrac{b \sin A }{\sin B}


a = \dfrac{10 \sin 150}{\sin 12} \approx 28.0
