Two similar triangles are congruent always, sometimes, or never?

Answers

Answer 1
Answer:

Two similar triangles are never congruent.  Similar triangles have the same shape, but their sizes may differ. They have corresponding angles that are equal and corresponding sides that are proportional to each other.

However, being similar does not guarantee that they are congruent.

Congruent triangles, on the other hand, have both the same shape and size. Their corresponding angles and sides are equal in length. Congruent triangles are essentially identical to each other.

In summary, similarity implies the same shape but different sizes, while congruence implies both the same shape and size. Therefore, two similar triangles are never congruent.

Answer 2
Answer:

congruency means, exact twins, completely exact.

similarity means, they must look the same only, one can be larger or smaller than the other, the angles must be the same, but the lengths can be longer or shorter and that's ok.

if two figures are congruent, they are also similar, but if one is larger than the other, they're still similar, though not congruent anymore.

Simplify by factorising first

Answers

Answer:

x+8

Step-by-step explanation:

Simplify the numerator

list the factors of 16

16: 1, 2, 4, 8, 16

look for two factors that add up to the b value

in this case it is 18

by looking at the factors 2 and 8 add up 10

so you can rewrite the numerator as x^(2)+2x+8x+16

Split the trinomial into two separate binomials each having one of the factors that add up to 10

So it should be x^(2) +2x and 8x+16

Factor both binomials

you can factor an x from the first one

Then it is x(x+2)

Factor an 8 from the second one

8(x+2)

So it should be x(x+2)  8(x+2)

This can rewritten as (x+8)(x+2)

So now you have ((x+2)(x+8))/(x+2))

simplify it by canceling out the two (x+2)'s

this is because (x+2)/(x+2) is 1

Finally you get x+8

Polygon MNOPQ is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image M′N′O′P′Q′. The coordinates of point M are (2, 4), and the coordinates of point N are (3, 5).What is the slope of M′N'?

Answers

First, we calculate the slope of MN:
= (5 - 4) / (3 - 2)
= 1
Dilation does not affect the slope of a line; therefore, the slope of M'N' is also 1.
Thank you for posting your math question here at brainly. The slope of M'N would be 1. Below are the choices that can be found elsewhere:

a. √2
b. 1
c. √3
d. √1/2

Below is the solution 

= (5 - 4) / (3 - 2)
= 1

A businessman has 10 employees. His salary is equal to 6 times the average of employees salaries. If the 11 of them receive a total of $64,000 in one year, what was the business mans salary that year ??  a) $4000, b) $6000, c) $24,000, d) $ 40,000, e) $44,000

Answers

business man's salary = x
employee's salary = y

x + 10y = 64000
x = 6y

(6y) + 10y = 64000
16y = 64000
y = 4000

x = 6(4000)
x = 24000

Answer: (c) $24,000

Which r–value represents the strongest negative correlation?A. –0.7
B. –0.22
C. 0.38
D. 0.9

Answers

The best answer to the statistics question above would be letter A. The r-value that represents the strongest negative correlation among the given choices would be -0.7. This is because the magnitude of the correlation ranges from .7 to .9 which indicates a strong correlation. The negative sign connotes the negative relationship.

Answer:

A.
