Please help me soon. I don't know how to find the shortest distance. Would it be the line from T to the 'center' of ABC? If it is, I don't know how to find the center of ABC.

Which polynomial represents the area of the rectangle? http://prntscr.com/ku2v2m

2x2−9x−10

2x2−x−10

2x2+x−10

2x2−10

(2x+5)(x-2)=2x^2+x-10.

Help please.

$\frac{10}{7}\div4=\frac{10}{7}\cdot\frac14=\frac{10}{28}=\frac{5}{7}$

I still need help on this problem.

Let  $x\mathbin{\spadesuit}y = x^2/y$ for all $x$ and $y$ such that $y\neq 0$. Find all values of $a$ such that $a\mathbin{\spadesuit} 3 = 9$. List the values you find in increasing order, separated by commas.

Since $a\mathbin{\spadesuit} 3 = 9$, we know that $\frac{a^2}{3^2}=9$. Simplifying this gives us $\frac{a^2}{9}=9$. When we multiply by 9 on both sides, we get $a^2=81$. So, $a=-9,9.$

I think you mean -(11 1/9)
