Kin made a Picture frame for a square picture with sides that are 5f-4 inches long. Framing the picture adds 2 inches to the len
elena-s [515]

The perimeter of a shape is the sum of its side lengths

The expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

<h3>How to determine the perimeter of the shape</h3>

The side length of the frame is given as l

So, the perimeter of the frame is

:P = 4l

When 2 inches are added to each length, the perimeter of the frame becomes

P =4(l + 2)

Expand

P =4l + 8

Hence, the expressions for the perimeter of the frame are 4(l + 2) and 4l + 8

A,B and C are the vertices of one triangle.
dsp73

Answer:


Step-by-step explanation:

Given: The triangle with coordinate A(4,6), B(2,-2) and C(-2,-4). D is the mid point of AB and E is the mid point of AC.

To prove: DE is parallel to BC.

Construction: Join DE.

Proof: If we prove the basic proportionality theorem that is \frac{AD}{DB}=\frac{AE}{EC}, then it proves that DE is parallel to BC.

Now, Mid Point D has coordinates=(\frac{4+2}{2},\frac{6-2}{2})=(3,2) and Mid Point E has coordinates=(\frac{4-2}{2},\frac{6-4}{2})=(1,1)

Now, AD= \sqrt{(4-3)^{2}+(6-2)^{2}}=\sqrt{17}

DB=\sqrt{(3-2)^{2}+(2+2)^{2}}=\sqrt{17}

AE=\sqrt{(4-1)^{2}+(6-1)^{2}}=\sqrt{34}

EC=\sqrt{(1+2)^{2}+(1+4)^{2}}=\sqrt{34}

Now, \frac{AD}{DB}=\frac{AE}{EC}

=\frac{\sqrt{17}}{\sqrt{17}}=\frac{\sqrt{34}}{\sqrt{34}}=\frac{1}{1}

Hence, \frac{AD}{DB}=\frac{AE}{EC}

Thus, By basic proportionality theorem, DE is parallel to BC.
