Can someone help me out my grads are bad

Lisa's new area will be 3600 ft ^ 2

It will be 9 times the original

Dan should increase the length by 5 times

Step-by-step explanation:

Original length = 40

New length = 40 x 3 = 120

Original length = 10

New length = 10 x 3 = 30

120 x 30 = 3600 ft^2

3600/400 = 9

It will be 9 times larger

For Dan:

ex:

length = 1

width = 2

Area = 2

He wants it to be 20 times 2

Lisa says increase 4 times

2 x 4 = 8

2 x 20 = 40

40/8 = 5

If my answer is incorrect, pls correct me!

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
