Answer:

the perimeter is 960

Step-by-step explanation:

The computation of the perimeter is shown below;

If we assume

= (24 × 2) + (6 × 2)

= 48 + 12

= 60

And, the area is 16 times to that of original So

= 60 × 16

Hence, the perimeter is 960

PLEASE HELP ME NOW!!

puteri [66]

Answer:

$x=4+-2\sqrt{7}$

Step-by-step explanation:

To solve, we need to take square root of both sides first:

$(x-4)^2=28\\\sqrt{(x-4)^2} =+-\sqrt{28} \\x-4=+-\sqrt{28}$

Now we use the property of radical shown below to simplify square root of 28:

Property: $\sqrt{x*y}=\sqrt{x} \sqrt{y}$

Now, we have:

$x-4=+-\sqrt{28}\\x-4=+-\sqrt{4*7}\\x-4=+-\sqrt{4}\sqrt{7}\\x-4=+-2\sqrt{7}$

Now we take 4 to the other side and isolate x:

$x-4=+-2\sqrt{7} \\x=4+-2\sqrt{7}$

first answer choice is right.
