12 × 2 = 24
24 × 3 = 72
72 × 4 = 288
288 × 5 = 1,440, and so on...

Let's call Frank's house F, Derek's one D n Evan's E.
F(5,-4)
E(-3,-4)
D(-3,4)
FE=5-(-3)=5+3=8
ED=4-(-4)=4+4=8
We can see the triangle is a half of a square, so FD is 8(√2)≈11.312
11.312+8=19.312
The answer is C.19.31
The solution of given inequality is: 
<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>

We have to find the value of "x"
<em><u>Let us solve the given inequality</u></em>
Divide both sides of inequality by 7

<em><u>Simplify the above expression</u></em>




Thus the value of x is
