[Done] The equation [tex]a=\frac{1}{2}\left(b_1+b_2\right) h[/tex] can be used to determine the area, [tex]a[/tex], of a trapezoid with height, [tex]h[/tex], and base lengths, [tex]b_1[/tex] and [tex]b_2[/tex]. Which are equivalent equations? Check all that apply. [tex]\frac{2 a}{h}-b_2=b_1[/tex] [tex]\frac{a}{2 h}-b_2=b_1[/tex] [tex]\frac{2 a-b_2}{h}=b_1[/tex] [tex]\frac{2 a}{b_1+b_2}=h[/tex] [tex]\frac{a}{2\left(b_1+b_2\right)}=h[/tex]

[Done] Consider the following function: [tex]f(x)=\left\{\begin{array}{ll} \frac{x^2-2 x-24}{x+4} & \text { if } x \neq-4 \\ -2 & \text { if } x=-4 \end{array}\right.[/tex] Determine if [tex]f(x)[/tex] is continuous at [tex]x=-4[/tex]. If not, select the option with the correct reasoning as to why not. A. Continuous at [tex]x=-4[/tex] B. Not continuous at [tex]x=-4[/tex] because [tex]\lim _{x \rightarrow-4} f(x) \neq f(-4)[/tex] C. Not continuous at [tex]x=-4[/tex] because [tex]\lim _{x \rightarrow-4} f(x)[/tex] does not exist D. Not continuous at [tex]x=-4[/tex] because [tex]f(-4)[/tex] is undefined
