Write an expression for the area of this figure.
Write the expression in its simplest form.

Simplify the expression: 7+3(1 - 2x) 

• 21 - 6x
• 10 - 2x
• 10 - 20x
• 10 - 6x

 $Expand\ and\ Simplify:\ \left(x+6\right)\left(x+2\right)$  

•  $x^2+4x+12$  

•  $x^2-2x+12$  

•  $x^2+8x+12$  

• None of the Above.

 $\frac{2y}{3}-\frac{y}{4}$  

•  $\frac{11y}{12}$  

•  $\frac{5y}{12}$  

•  $\frac{y}{12}$  

•  $\frac{12}{y}$  

P = 6x + 2

Express x in terms of P

• $x\ =\ \frac{P-2}{6}$

• $x=\frac{P+2}{6}$

• $x\ =\ \frac{P+6}{2}$

• $x\ =\ \frac{\left(P-6\right)}{2}$

Make x the subject of equation:

 $y^2=x^2+c^2$  

•  $\sqrt{y^2-c^2}$  

•  $\sqrt{y^2+c^2}$  

•  $y^2-c^2$  

•  $y^2+c^2$
