The ordered pair (3, 2) satisfy the both inequalities it means it lies in the intersection region of both the inequality option (A) is correct.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have inequality:

2x + 4y ≤ 12

3x - y < 2

Plug (-3, 2) in the above inequality:

2(-3) + 4(2) ≤ 12

-6 + 8 ≤ 12

2≤ 12 (True)

3(-3) - 2 ≤ 12

- 9 - 2 ≤ 12

-11 ≤ 12 (True)

Similarly, we can check for other inequalities.

Thus, the ordered pair (3, 2) satisfy the both inequalities it means it lies in the intersection region of both the inequality option (A) is correct.

The formula for the volume V of a rectangular prism is V = ℓwh, where ℓ represents the length, w represents the width, and h rep
UkoKoshka [18]

Answer: w=\dfrac{V}{lh}

Step-by-step explanation:

Given: The formula for the volume V of a rectangular prism is V = ℓwh, where ℓ represents the length, w represents the width, and h represents the height.

We rearrange this formula by dividing  ℓh both sides of the formula to get the new formula for the width of the rectangular prism, we get'

w=\dfrac{V}{lh}

Hence, the new formula for the width of the rectangular prism. :

w=\dfrac{V}{lh}

Leap years are years in which February has 29 days instead of 28. The device of leap year was invented to keep the calendar in s
goldenfox [79]

Answer:

As you know, a year has around 365 + 1/4 days.

This means that in two years, we have:

365 + 356 + 1/4 + 1/4 = 730 + 1/2

and so on.

adding this up, when we have 4 years we have a full day extra, this is:

1460 + 1

When we divide 1461 by 4, we have 365 with a surpass of 1.

The rule used to keep the calendar in sync with this extra day is adding an extra day to each fourth year.

So each fourth year, we have an extra day in Februray (the Februray 29th), this is called a bisiest year.

The "math rule" used to know if a year is leap or not is:

if a year is not divisible by 4, then it is a common year

else if the year is not divisible by 100 then it is a leap year,

else if the year is not divisible by 400, then it is a common year

if not, the year is a leap year.

Where "year" represents the number of the year.
