Find the area of the shape shown below.<br> 7<br> 3<br> 3
kumpel [21]

Split it into two shapes a square and a triangle.

Square =  3 x 3 = 9

Triangle = 1/2 x base x height

The height would be the side of the square = 3

The base would be the length of the top line minus the length of the side of the square = 7-3 = 4

1/2 x 4 x 3 = 6

Total area = 6 + 9 = 15 square units.

What is the sign of s^67/t^9 when s &lt; 0 and t &gt; 0?
Sphinxa [80]

Here, there are 67 (an odd number) negative factors, so the expression will be negative.
