Answer:

our answer is  \sqrt{4}*\sqrt{15} or in simplified form

as 2*\sqrt{15}

Step-by-step explanation:

\sqrt{60}

We need to solve the above expression

Factors of 60:

1X60,  2X30, 3X20, 4X15, 5X12, 6X10

We need two factors one of which is perfect square

From the above factors only 4X15 full fills our condition as 4 is a perfect square

\sqrt{60}\\ =\sqrt{4 * 15}\\ We\,\,know\,\, \sqrt{a*b}= \sqrt{a}*\sqrt{b}\\ =\sqrt{4}*\sqrt{15}\\

Solving, we get

2*\sqrt{15}

So, our answer is  \sqrt{4}*\sqrt{15} or in simplified form

as 2*\sqrt{15}

BRAINLIEST ANSWER GIVEN Without actually solving the​ problem, choose the correct solution by deciding which choice satisfies th
pochemuha

Answer:

<h2>length = 6 feet</h2><h2>width = 4 feet</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where l is the length

w is the width

The length of the rectangle is 2 feet longer than the width is written as

l = 2 + w

Perimeter = 20feet

So we have

20 = 2( 2 + w ) + 2w

20 = 4 + 2w + 2w

4w = 16

Divide both sides by 4

w = 4

Substitute w = 4 into l = 2 + w

That's

l = 2 + 4

l = 6

<h3>length = 6 feet</h3><h3>width = 4 feet</h3>

Hope this helps you
