What is the least prime number greater than 50?
uysha [10]
A prime number is a number that has only two factors: 1 and itself
For example, the number 7 has two factors: 1,7 This makes 7 a prime number
Since the number has to be greater than 50, we can go to the next whole number; 51
51 has four factors, 1,3,17,51 This is not our prime number
52 is even so obviously it's not prime because you can divide by two
53 has only two factors; 1,53 This means that its prime and the answer is 53 :)

A rectangle has an area of 171 square meters. Its width is ten meters less than the length. Find the measures of the length and
9966 [12]

Step-by-step explanation:

The area of a rectangle is 171 m²

Let l is the length and b is the width of the rectangle

It width is 10 m less than the length. So,

b = l-10 ...(1)

Area of a rectangle is given by :

A=l\times b\\\\171=l(l-10)\\\\l^2-10l=171\\\\l^2-10l-171=0\\\\l^2-19l+9l-171=0\\\\\text{taking common together}\\\\l(l-19)+9(l-19)=0\\\\(l-9)(l-19)=0

or

l = 9 m or l = 19 m

If l = 9 m,

b = 9-10 = -1 m (can't be possible)

If l = 19 m

b = 19-10 = 9 m

So, the length an the breadth of the rectangle is 19 m and 9 m respectively.

Simplify an expression for the perimeter of the rectangle shown.
Zanzabum

The perimeter of the rectangle is P = (17.2x₊16.4).

Given that,

Length, l = 8.6x₊3

Width, b = 5.2

In the formula P=2l+2w, where l is the rectangle's length and w is its width, the perimeter P of a rectangle is determined. Using the formula A=l×w, where l is the length and w is the width, we can determine the area A of a rectangle.

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of the rectangle is given by :

P=2(l₊b)

Putting values of l and b in the above formula:

p = 2(8.6x ₊ 3 ₊ 5.2)

= 2(8.6x ₊ 8.2)

= 2(8.6x) ₊ 2(8.2)

= 17.2x ₊ 16.4

So, the required perimeter of the rectangle is 17.2x₊16.4.
