Find the least number by which 243 must be divided to make it a perfect<br> square.
Anarel [89]

Is 243 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 243 is about 15.588. Thus, the square root of 243 is not an integer, and therefore 243 is not a square number.

Please solve this fast​
Korolek [52]

Step-by-step explanation:

1.

qr - pr \: + qs - ps

r(q - p) + s(q - p)

(r + s)(q  - p)

2.

{x}^{2}  + y - xy - x

{x}^{2}  -  x - xy + y

x(x - 1) - y(x - 1)

3.

6xy + 6 - 9y - 4x

- 4x + 6 + 6xy - 9y

2( - 2x + 3) - 3y( - 2x + 3)

(2 - 3y)( - 2x + 3)

4.

{x}^{2}  - 2ax - 2ab + bx

x(x - 2a) - b(x - 2a)

-(x +b)(2a-x)

5.

axy + bcxy - az - bcz

xy(a + bc) - z(a  + bc)

(xy  - z)(a + bc)

Which is an example of system of linear inequalities?.
labwork [276]

Example of  linear inequalities; y ≤ x – 1 and y < –2x + 1

A combination of linear inequality equations with the same variables is referred to as a system of linear inequalities.

There are five inequality symbols used to represent equations of inequality.

These are less than (<), greater than (>), less than or equal (≤), greater than or equal (≥), and the not equal symbol (≠). Inequalities are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable.

Example of  linear inequalities;

Graph the following system of linear inequalities:

y ≤ x – 1 and y < –2x + 1

Graph the first inequality y ≤ x − 1.

We will draw a solid border and shade below the line due to the "less than or equal to" mark.

On the same x-y axis, graph the second inequality, y -2x + 1.

In this instance, the less-than symbol will cause our boundaries to be dashed or dotted. Under the border, cast a shade.

As a result, the darker-colored zone extending indefinitely downward is the solution to this inequality problem, as seen below.

Kate scored 85,78,72, and 81 on 4 math tests. What score does she need on the fifth test to have at least an 80 average?
Elan Coil [88]

I am not good in this kind of question so maybe 84?

suppose the full marks for each of them is 100 so for 5 of them it will be 500 cause if you if you multiply 100 full marks by 5 it will be 500

so the answer to this question is maybe 84?

cause if you add all of them with 84 the outcome will be 400 and if you divide the 400 by 5 it will be 80
