Answer:
The answer to part A is 15 cm because you would first divide 16 by two to find the base of one triangle. Then you would do the pythagorean theorem to find the height. <em> I don't know if that would help.</em>
The answer to part B is 240 cm squared because you would find the area of one right triangle and multiply it by 4 to find the area of all the sides of the box.

Given: "2xy (x⁵)³ " ; Simplify .
_____________________________________
Note: (x ⁵) ³ = x⁽ ⁵ * ³ ⁾ = x ⁽¹⁵⁾ ;
______________________________________
Rewrite:
2xy (x⁵)³ = 2xy x⁽¹⁵⁾ ;
Rewrite:
2 * x * x⁽¹⁵⁾ * y ;
Note: "x * x⁽¹⁵⁾ = x¹ * x¹⁵ = x⁽¹ ⁺ ¹⁵⁾ = x¹⁶ ;
Rewrite: " 2x¹⁶ y " .

Since, <span>point K is the image of point J under a reflection across line L.
The distance, JM = MK
</span>Hence, 2x + 4 = 4x - 6
4x - 2x = 4 + 6
2x = 10
x = 5
Also refrection of a point across a line form an angle of 90 degrees at the point of refrection.
i.e. 3y - 30 = 90
3y = 90 + 30 = 120
y = 120 / 3 = 40
Therefore, the value of y is 40.
