How to solve inequalities when quadratic formula is needed?

1 answer:

6 0

First, treat the inequality as you would a normal equation. Solve for the different possibilities of x through the quadratic formula. Once you have the choices, you can write out the inequality sign back in and finish your solution. A better answer could be given with a specific question.

Which expression is another way to write √125x?

tatyana61 [14]

$\sqrt{125x}$

Here 125 can be written as $(5)(5)(5)$

$=\sqrt{(5)(5)(5)x}$

here $(5) (5)$ can be written as $5^{2}$

= $\sqrt{5^{2}(5)x }$

so it can be written as

$=5\sqrt{5x}$

A rectangle has a perimeter of 72 ft the side lengths are whole numbers what is the area

dimaraw [331]

Answer:

Minimum area is : 1 * 35 = 35

Maximum area is : 19 * 17 = 323

Step-by-step explanation:

The parameter (P) of rectangle is calculated using:

P = 2(a+b)

We are given that,

P = 72

=> 2(a+b) = 72

=> a+b = 36

In rectangle, the lengths of both sides are different and a whole number (as mentioned in question), Therefore, the length of smaller side a can be varied from 1 to 17. Similarly, the length of larger side varies from 19 to 35.

The area can be easily calculated using a*b.

Minimum area is : 1 * 35 = 35

Maximum area is : 19 * 17 = 323
