There should be \boxed{5{\text{ plants }}x} in each row so that there are 25 plants in the square.

Further Explanation:

The formula of area of square can be expressed as follows,

\boxed{Area = \left( s \right) \times \left( s\right)}

The formula of perimeter of the rectangle can be expressed as follows,

\boxed{{\text{Perimeter}} = 4 \times s}

Here, s represents the side of square.

Given:

There should be 25 plants end up in a square.

Explanation:

Consider the number of rows as x.

The number of rows can be expressed as follows,

\begin{aligned}{x^2} &= 25\\x &= \sqrt {25}\\x &= 5\\\end{aligned}

There should be \boxed{5{\text{ plants }}x} in each row so that there are 25 plants in the square.

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,

Which of the following is a solution to 2cos2x − cos x − 1 = 0?
Pavel [41]

Answer:

Option A is correct.

Solution for the given equation is, x = 0^{\circ}

Step-by-step explanation:

Given that : 2\cos^2x -\cos x -1 =0

Let \cos x =y

then our equation become;

2y^2-y-1= 0           .....[1]

A quadratic equation is of the form:

ax^2+bx+c =0.....[2] where a, b and c are coefficient and the solution is given by;

x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}

Comparing equation [1] and [2] we get;

a = 2 b = -1 and c =-1

then;

y = \frac{-(-1)\pm \sqrt{(-1)^2-4(2)(-1)}}{2(2)}

Simplify:

y = \frac{ 1 \pm \sqrt{1+8}}{4}

or

y = \frac{ 1 \pm \sqrt{9}}{4}

y = \frac{ 1 \pm 3}{4}

or

y = \frac{1+3}{4} and y = \frac{1 -3}{4}

Simplify:

y = 1 and y = -\frac{1}{2}

Substitute y = cos x we have;

\cos x = 1

⇒x = 0^{\circ}

and

\cos x = -\frac{1}{2}

⇒ x = 120^{\circ} \text{and} x = 240^{\circ}

The solution set:  \{0^{\circ}, 120^{\circ} , 240^{\circ}\}

Therefore, the solution for the given equation  2\cos^2x -\cos x -1 =0 is, 0^{\circ}

What is the area of this trapezoid?
timofeeve [1]

Answer: 140 in^{2}

Step-by-step explanation:

The area for a trapeziod is A = \frac{1}{2}(b1+b2)h

We have almost everything we just need the total length of the top base, since it gives us the outer lengths we can find that by simply doing 4+6+15 which turns out to be 25

Now we can plug in our values:

A = \frac{1}{2}(25 + 15) x 7 = 140in^{2}
