Tell whether the pair of polygons is similar. Explain why or why not.
Savatey [412]

9514 1404 393

Answer:

  not similar

Step-by-step explanation:

Similar polygons have all corresponding angles congruent, and corresponding sides proportional.

The sides lengths guarantee the polygons are parallelograms, so one pair of angles being congruent is sufficient to ensure that all corresponding angles are congruent.

The ratio of side lengths in the left polygon is 13/8, and the ratio of side lengths in the right polygon is 5.2/2.4 = 13/6. These are different ratios, so the corresponding sides are NOT proportional.

The figures are NOT SIMILAR.

When solving the equation, which is the best first step to begin to simplify the equation?
boyakko [2]

Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)

Cindy's age, x, is 3 times her age 6 years ago which equation represents the statement x=3(x-6) or x=3-6x or x=3x-6 or x=3x+6
WINSTONCH [101]
Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago. 
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the  present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
