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)? expr
AnnZ [28]

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)

<h3>Further explanation </h3>

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 x^2.

Since there are 25 total plants, the correct value of x will satisfy the equation x^2 = 25

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.

x^2 = 25, so x = 5,

3 is incorrect, should be 28.9

16^2 + 18^2 = EG^2
256 + 324
580 = EG^2
EG ≈ 24.08

16^2 + 24.08^2 = AG^2
256 + 580 = AG^2
836 = AG^2
AG ≈ 28.9

5 is incorrect:

The base is 8.
Draw an altitude the base.
Since the triangle is isoceles, it divides the base in half.
Half of that base is 4.
Two right triangles have been formed with one leg 4 and hypotenuse 8.
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b ≈ 6.93

The height of the triangle is 6.93, the base is 8.
A = bh/2 = 8*6.93/2 ≈ 27.7 ≈ 28
