a) $2 x \cdot 2 - x + 4$ $2x*2-x+4$

The degree of the expression is 1 since the highest power is 1.

b) $2 x \cdot 2 - x + 4$ $color(red)(" 2"x*"2")color(magenta)( - x)color(darkred)( " + 4"$

There are 3 terms as u can see above.

c) $2 x \cdot 2 - x + 4$ $2x*2-x+4$

When $x = - 2$ $x=-2$

$\Rightarrow 2 (- 2) \cdot 2 - (- 2) + 4$ $=>2(-2)*2-(-2)+4$

$\Rightarrow - 8 + 2 + 4$ $=>-8+2+4$

$\Rightarrow - 2$ $=>-2$
