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?
Question
Answer:
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
