Problem 1, part (a)

<h3>Answer: False</h3>

For instance, 200 feet in real life can be reduced to scale down to say 2 inches on paper. So we have a reduction going on, and not an enlargement.

====================================================

Problem 1, part (b)

<h3>Answer: true</h3>

This is because a scale drawing involves similar polygons. This is true whenever any dilation is applied.

====================================================

Problem 2

I'm not sure how your teacher wanted you to answer this question. S/he didn't give you any numbers for the side lengths of the polygon. The angle measures are missing as well.

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~

Generally what I like to do, to solve questions like this is to substitute the given answers into the equation to solve this faster...

Equation: x^2 + 10x + 12 = 36

A.) (-12)^2 + 10(-12) + 12 = 36

144 - 120 + 12 = 36

24 + 12 = 36

36 = 36

(2)^2 + 10(2) + 12 = 36

4 + 20 + 12 = 36

24 + 12 = 36

36 = 36


Since we found the answer with the first try, we already know the correct answer is A.

So...

The Correct answer is: A.) x=-12 or x=2

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of t
alex41 [277]

Answer:

\angle MKJ  = 34

Step-by-step explanation:

Given

\angle LKJ = 124

Required

Find \angle MKJ

From the attachment:

The measure of \angle MKJ is calculated using the following expression:

\angle MKJ  + \angle LKM = \angle LKJ

Where

\angle LKM = 90 -- right-angled.

The expression becomes

\angle MKJ  + 90 = 124

\angle MKJ  = 124 - 90

\angle MKJ  = 34
