A square part of side 20 meters has a footpath along the boundary of width 10 meters . Find the area of path
qaws [65]

Answer:

Answer: 84 meters squared. (i.e. 84m^2).

Step-by-step explanation:

Area of the path = total area of path and plot - plot area only

First, let’s find the area of the plot:

20m x 20m = 400m^2

The path is 1m wide and runs all the way around, so, it describes an ‘outer square’ of 22m x 22m (2 x 1m larger because there are 1m of the path on each side).

The area of this ‘outer square’ is equivalent to the ‘total area of path and plot’

22m x 22m = 484m^2

So:

Area of the path = total area of path and plot - plot area only

= 484 - 400 = 84m^2

Your math teacher asked you to solve the equation in the box.
lawyer [7]

Answer:

x = x - 4/6

false

Step-by-step explanation:

6(x - 1) - 4x = 2(3x - 5)

First, lets distribute the 6 to each item inside the parentheses on the left side. You can do this by multiplying the 6 by each term.

6 * x = 6x

6 * -1 = -6

6x - 6 - 4x = 2(3x - 5)

Next, we will combine like terms.

6x - 4x = 2x

2x - 6 = 2(3x - 5)

Now, let's look at the right side of the equation.

Let's distribute the 2 to each item inside the parentheses on the left side. You can do this by multiplying the 2 by each term.

2 * 3x = 6x

2 * -5 = -10

6x - 1 = 6x - 5

Immediately, we can tell this is false, but let's solve the equation just to make sure.

6x - 1 = 6x - 5

+1              +1

6x = 6x - 4

---     --------

6        6

x = x - 4/6

This is false.

Find the equation of the line through the given pair of points. (-7,-6) and (-4,9)
Softa [21]

Answer:

y=5x+29

Step-by-step explanation:

1. find slope

y2-y1/x2-x1

9--6/-4--7= 15/3=5

2. substitute x and y

(-4, 9)= 9=5(-4)+b

            9=-20+b

             29=b

3. put it together

y=5x+29
