20 - 4 - 2 = 14. A negative number is just like subtracting it.

Answer:C or 11

Step-by-step explanation:

3x²-1

First you insert x... which is 2

3(2)²-1

then you square the 2. (multiply it by itself)

3(4)-1

Then you multiply 3 by 4 to get 12

12-1

And then you subtract for your answer

$m\angle B=m\angle C\\
m\angle C=180-100=80 \Rightarrow m\angle B=80$

$\text{Given that,}\\\\4(x-3) +5x -x^2\\\\\text{For x =3,}\\\\4(3-3) +5(3) -3^2 = 4(0) +15 -9 = 6$

first you would do this

4x6=24

then,4x30=120

then,10x30=300

then 10x6=60 lastly you would add them up and get a sum of 504
