The Pythagorean theorem is used to find the length of a line segment based on its coordinates:
  d = √((x2-x1)² +(y2-y1)²)

AB = √((-1-4)² +(4-(-1))²) = √50 ≈ 7.1
BC = √((0-(-1))² +(-3-4)²) = √50 ≈ 7.1
CA = √((4-0)² +(-1-(-3))²) = √20 ≈ 4.5

Adding these numbers for the side lengths, we get
  P = 7.1 + 7.1 + 4.5 = 18.7


_____
Saving rounding until the end, as we should, the result would be 18.6. The instructions specifically tell us not to do that.

A square has a perimeter of 40 m what is the length of each side
zubka84 [21]

Answer:

10m

Step-by-step explanation:

<u>Perimeter</u> means adding up all of the sides of a shape.

One property of a square is that <u>all lengths of a square are the same</u>.

We also know squares have <u>4 sides</u>.

<u />

Lets set up an expression to solve the length for each side with variable S representing the length of a side:

4 * S = 40

Divide each side by 4:

S = 10

Therefore, each side of the square has a length 10m

4. Line t and AECA and AFDB are shown on the coordinate plane
julia-pushkina [17]

Answer:

A, B, C, E

Step-by-step explanation:

It can be seen from the figure that the points A, B, C and D, all are lying in the line t.

=> So that it can be concluded that AC and BC and BD have the slopes which are equal to each other and also equal to the slop of line t

So that all answer A, B, C are true.

In addition, as FD is parallel with x - axis, so that slope of the line t is equal to <em>tan angel FDB </em>

As FDB is the right triangle with BFD = 90°

=> tan angel FDB = FB/ FD (tan of an acute angel in the right triangle = opposite side/ adjacent side)

=> Slope of the line t is equal to FB/ FD

=> Answer E is true
