What is the perimeter of this rectangle?

Mathematics

Alenkinab [10]3 years ago

Answer:

A.

Step-by-step explanation:

I see the bottom vertices are (x1, y1) and x2, y1).

I assume the top vertices are (x1, y2) and (x2, y2).

If that is correct, the the lengths of the top side and bottom side are x2 - x1.

The lengths of the left side and right side are y2 - y1.

Since there are two horizontal sides and two vertical sides, the perimeter is:

2(x2 - x1) + 2(y2 - y1)

Answer: Choice A.

Drag each expression to show whether it is equivalent to −2.6−(−5.9) -2.6 x - -5.9 x , −2.6+(−5.9) -2.6 x + -5.9 x , or neither.
vredina [299]

Answer:

-2.6x-(-5.9x) is equivalent to -2.6x+5.9x and 5.9x+(-2.6x)

-2.6x+(-5.9x) is equivalent to -2.6x-5.9x and -5.9x+(-2.6x).

The expressions which are equivalent to neither:

-5.9x+2.6x and 5.9x-(-2.6x)

Step-by-step explanation:

Given the expressions:

1) -2.6x-(-5.9x)

2) -2.6x+(-5.9x)

To find:

The expressions equivalent to the given expressions.

or the expressions which are not equivalent to any of the given expressions.

Solution:

First of all, let us solve the brackets from the given expressions.

-2.6x-(-5.9x) can be written as -2.6x+5.9x (because when we multiply a negative sign with negative, it becomes positive.)

Similarly -2.6x+(-5.9x) can be written as -2.6x-5.9x (because when we multiply a positive sign with negative, it becomes negative.)

Therefore, the answer is:

-2.6x-(-5.9x) is equivalent to -2.6x+5.9x and 5.9x+(-2.6x)

-2.6x+(-5.9x) is equivalent to -2.6x-5.9x and -5.9x+(-2.6x).

The expressions which are equivalent to neither:

-5.9x+2.6x and 5.9x-(-2.6x)
