I need help with these two questions

Given

Step-by-step explanation:

The Lateral surface area is the surface area of only 4 sides of the figure, that is, area excluding top and bottoms sides.

Lateral surface area of cuboid

= 2h (l+b)

where h is height

b is breadth

l is length

= 2*12 (5+4)

= 2*12*9

= 216 m^2

Lateral surface area of cube

= 4s^2

where s is the side

= 4*(2)^2

= 4*4

= 16m^2

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
