Similar polygons only differ by a scaling factor. In other words, two polygons are similar if one is the scaled version of the other.

In particular, this implies that the angles are preserved, and the correspondent sides are in proportion.

These two polygons are both rectangles, so the angles are preserved. We must check the sides, and we have to check if the smaller sides are in the same proportion as the bigger sides.

So, the two rectangles are similar if the following is true.

4\div 5 = 11\div 12

In any proportion, the product of the inner terms must be the same as the product of the outer terms:

4\cdot 12 = 5\cdot 11 \iff 48=55

This is clearly false, and thus the two rectangles are not similar.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
Zepler [3.9K]

First let’s put 5x+2y = 12 into slope-intercept form.

2y = -5x + 12

y = (-5/2)x + 6

So any line that is parallel to y = (-5/2)x + 6 must have a slope of -5/2.

Our answer then is y = (-5/2)x + c

Now all that remains is to find out the value of c.

We know this line passes through the point (-2,4). Which means when x = -2, y = 4.

4 = (-5/2)(-2) + c

4 = 5+c

c = -1

Hence the line you want is y = (-5/2)x - 1

Since the question gave the line in standard form and didn’t ask for any particular form, let’s give the answer in the same form that the question asked.

2y = -5x - 2

5x + 2y = -2

Write an equivalent expression for -3t+4q+5t-7q
steposvetlana [31]

Answer:

The equivalent expression can be given as:

⇒  2t-3q

Step-by-step explanation:

Given expression:

-3t+4q+5t-7q

To write an equivalent expression:

Solution:

In order to write an equivalent expression, we will combine the like terms. By like terms, we mean the terms with the same variable constant.

For example : 5x and -3x  are like terms.

We have:

-3t+4q+5t-7q

Combining like terms :

⇒ -3t+5t+4q-7q

⇒  2t-3q

Thus, the equivalent expression can be given as:

⇒  2t-3q

Hi there! Sorry to bother you, but can someone help me out with this? (the number 7 to 10)
maksim [4K]

Answer:

7. <K = <R

8. PR = JK

9. <A = <X

10. TX = AB

For question 7, find the angle that looks the most similar to the angle in the question.

For question 8, since the sides (not the hyp.) are equal, PR will be equal to any of those two.

For question 9, the triangles are positioned differently, but it is the angle with two angle lines on it.

Lastly, for question 10, TX will be the same length as the shortest side in the corresponding triangle.
