For which value of x must the square root <br><br> 97x<br><br> be further simplified

lys-0071 [83]

Question:

For which value of x must the expression √97x be further simplified?

A. 5 B. 10 C. 15 D. 20

Answer:

$D.$ $x = 20$

Step-by-step explanation:

Given

$\sqrt{97x$

Required

For what value of x can it be simplified

From the list of options, only (D) is correct

D. 20

Substitute 20 for x in $\sqrt{97x$

$\sqrt{97 x} = \sqrt{97 * 20}$

Express 20 as 4 * 5

$\sqrt{97 x} = \sqrt{97 * 4 * 5}$

Reorder

$\sqrt{97 x} = \sqrt{4 *97 * 5}$

Split

$\sqrt{97 x} = \sqrt{4} *\sqrt{97 * 5}$

$\sqrt{97 x} = 2*\sqrt{97 * 5}$

$\sqrt{97 x} = 2*\sqrt{485}$

$\sqrt{97 x} = 2\sqrt{485}$

With other values of x, the given expression can not be simplified.

Hence:

$x = 20$

Can someone help me with this?

Mandarinka [93]

Answer:

Step-by-step explanation:

Area of rectangle = length * width

= (x + 4) (5x)

= x *5x + 4 *5x

= 5x² + 20x

Perimeter of rectangle = 2*(length + width)

= 2*(x + 4 + 5x)

= 2*(6x + 4)

= 2*6x + 2 *4

= 12x + 8
