Answer: B.

Y = 4x

Step-by-step explanation:

Given that the side of a shape is x

The perimeter of the shape is y

Perimeter of a rectangle can be expressed as:

P = 2L + 2W

Where L = length and W = width

But if the shape is a square, and the side of the shape is x, then, the perimeter will be

P = 4x

Where perimeter P = Y

Therefore, perimeter Y will be;

Y = 4x

Therefore, the correct answer is B which is:

Y = 4x

What is the answer for -7x= -96
Darina [25.2K]

Hello!

To solve, this, perform the opposite operation of what is being done on both sides. Here, we see x being <u>multiplied</u> by -7. The opposite operation of multiplication is division.

Therefore, to solve this, divide both sides by -7.

-7x = -96

-7x / -7 = -96 / -7

x = -96/-7

When you divide two negative numbers, they become a positive.

x = 96/7

This cannot be simplified further as a fraction, but if you would like the exact decimal, it is about 13.714.

Hope this helps!

I know how to do this and the teacher don't teach it right so I don't get how to do it at all
Kobotan [32]
I dont have time to do all of these right now my apolgies but Ill explain how to do it.

The 3 angles of a triangle add up to 180.

So let me show you how to do 1.
.
.
.

1. 58 degrees

92, 30, ?

If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58

So we now know the last angle is 58 degrees because

92+30+58=180

When Colton commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a
N76 [4]

Answer:

(34, 48)

Step-by-step explanation:

According to the Empirical Rule, 95% of normally distributed data lie within two standard deviations of the mean.  That, in turn, means 95% of the data in this problem lie within 2(3.5 min), or 7 min, of the mean:

41 - 7 < mean < 41 + 7, or

34 < mean < 48, or simply (34, 48)
