I think it might be x + b square
Answer: <em>54 inches</em>
Step-by-step explanation:
<em>Let's take the equation for the area of a right triangle</em>

<em>A=a*b/2</em>
<em>A=12*9/2</em>
<em>A=108/2</em>
<em>A=54</em>
Answer:
b
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept
You know that 8 = 2x2x2 so you would need 2^3 to be your answer, so x = -1
