Answer:

6 hours

Step-by-step explanation:

What we must do is calculate the speed of each one,

Melissa in one hour plants 10 trees, that is 10/1 is her speed.

Jane in two hours plants 17 trees, that is 17/2 is her speed.

Now, we want to know the time it takes to plant 11 trees, so the sum of the previous speeds is equal to 111 / x

10/1 + 17/2 = 111 / x

18.5 = 111 / x

x = 111 / 18.5

x = 6

Which means that in 6 hours between the two they can plant 111 trees

Bao Yu is completing the square to solve the polynomial equation.
irga5000 [103]

Solution:

The square of the given equation can be completed as below:

Here we will make the terms on left hand side such that it gets the form of a^2\pm2ab+b^2=(a\pm b)^2

x^2-x-3=0\\\\\text{Isolate the constant}\\\\x^2-x=3\\\\x^2-2\times\frac{1}{2}\times x +\frac{1}{2}^2=3+ \frac{1}{2}^2\\\\(x-\frac{1}{2})^2=\frac{13}{4}\\

Hence the correct option is isolating the constant , -3.

Find the dimensions of the rectangle with area 289 square inches that has minimum perimeter, and then find the minimum perimeter
nalin [4]
 <span>To minimize the perimeter you should always have a square. 
sqrt(289) = 17 
The dimensions should be 17 X 17 

To see , try starting at length 1, and gradually increase the length. 
The height decreases at a faster rate than the length increases, up until you reach a square. 

Or if you want to use algebra, Say the width is 17-x 
Then the length is 289/(17-x) 

Now, this is bigger than 17+x, as shown here: 
289/(17-x) > 17+x 
289 > 289 - x^2 
which is true. 
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17 

Again, the dimensions should be a square. 17 X 17.</span>
