The reason why it is important to keep each side of a problem the same is because if you do, your problem will be unequal. This will mess the whole problem up.
Hope this Helps!

ABC is the right angle which is the side you have to write
Answer:
f(-1)=3
Step-by-step explanation:
f(x)=x^2-6x+3x-1
f(x)=x^2-3x-1
f(-1)=(-1)^2-3(-1)-1
f(-1)=1+3-1
f(-1)=4-1
f(-1)=3
X= 130 degrees since 180 is the total minus 50 from above
X + 9 = 2x - 3
<u>-x -x </u>
9 = x - 3
<u> +3 +3</u>
12 = x
