Raj has a small rectangular garden area as shown in the figure. He wants to expand the garden by doubling the length and width. He will then add 5 inches of soil to the entire area. How much soil does Jake need to get at the nursery?
2,160 in.3
2,700 in.3
5,340 in.3
10,800 in.3

10,800

Step-by-step explanation:  

i. Multiply 36 * 2=72

ii. multiply 15 * 2=30

iii. multiply both of them together and multply it by 5

72*30*5=10,800

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
