Q:

How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? express your answer as an integer?

Accepted Solution

A:
There are 5 plants x that should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)Further explanation Maria wants to plant a small tomato garden in her yard. She bought 25 tomato plants, and she has  read that ideally tomatoes are planted in a square grid to help them pollinate each other, as shown in the picture below.How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x  plants in each of x rows)?  Express your answer as an integer.If the gardener has x plants in each of her x rows, then the total number of plants will be [tex]x^2[/tex]. Since there are 25 total plants, the correct value of x will satisfy the equation [tex]x^2 = 25 [/tex] By taking the square root of both sides and note that 25 has both a positive and a negative  square root because you can't have a negative number of plants, hence you only want the positive square  root:You can solve this part simply by simple arithmetic.[tex]x^2 = 25,  [/tex] so [tex]x = 5,  [/tex] Learn moreLearn more about  Quadratic Equations Answer detailsGrade:  9Subject:  mathematicsChapter:   Quadratic EquationsKeywords:   Quadratic Equations
