The length, dm, of a rectangular field is 40m gester than the width The perimeter of the field is 400 m.

The sides would be: Length: 80 | Width: 120

Step-by-step explanation:

Basically, you know that L = W + 40. (Because length is 40 more than width)

and the perimeter of any triangle is 2L+2W.

In this case, the equation would be 2L + 2W = 400 | (perimeter is 400)

We also know that L = W + 40, so we substitute this equation as L in the above equation, to get 2(W+40) + 2W, which simplifies to 4W+80=400.

Solve, and we get W = 120. Subtract 40 to get length (120-40=80) so

L = 80 | W = 120

i dont know sorry

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
