<h3>What is integer?</h3>

An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Zero is not a fraction or decimal of any number. It is neither positive nor negative.

Given:

Set D is the set of positive two-digit even numbers less than 25 that do not contain the digit 0.

According to given question we have

2-digit numbers are the numbers that have two digits and they start from the number 10 and end on the number 99.

Starting at 12 going up the two digit numbers even numbers less than 25 that do not contain the digit 0.

12,14,16,18,22,24

Therefore, the required set of positive two-digit even numbers less than 25 that do not contain the digit 0 is 12,14,16,18,22,24.

Gardener has 780 plants. He wants to plant there in such a way that the number of rows and the numbers of columns remains same.

AleksAgata [21]

Answer:

<em>Gardener will need 4 more plants.</em>

Step-by-step explanation:

Gardener has 780 plants and wants to plant them in an array of n rows and n columns.

The number of plants needed to do that is:

$n*n=n^2$

He actually has 780 plants, thus it should occur:

$n^2=780$

Taking the square root:

n=27.9

Since n needs to be an integer, we round up n to get

n=28

But $28^2=784$ , 4 more than the actual number of plants, thus:

Gardener will need 4 more plants.

Note: There are other possible results for n. If we set n=29, then $n^2=841$ and Gardener would need 841-780=61 more plants, but the question asked for the minimum number of plants.
