A rectangular room twice as long as it is wide would contain 160 square feet more if each side were one foot longer. what is the

Blababa [14]

Length= 2*width

area=l*w=2*width*width=2*width^2
area+160=(2*width+1)*(width+1)
A+160=2w^2+2w+w+1
A+160=2w^2+3w+1
putting value of a
2w^2+160=2w^2+3w+1

The area of circle K when c=24x^2 pi

Gala2k [10]

Answer: $\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi },\:x=-\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi }$

Step-by-step explanation:

$c=24x^2 pi$

Switch sides:

$24x^2\pi =Kc$

divide both sides by $24\pi$

$\frac{24x^2\pi }{24\pi }=\frac{Kc}{24\pi }$

simplify:

$x^2=\frac{Kc}{24\pi }$

$x^2=\frac{Kc}{24\pi }$ $x=\sqrt{\frac{Kc}{24\pi }},\:x=-\sqrt{\frac{Kc}{24\pi }}$

answer: $x=\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi },\:x=-\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi }$

i hope it's help!

What is the answer? What does the symbol mean??

madam [21]

Answer:

6 or -6

Step-by-step explanation:

The symbol √ is the square root symbol.

The square root of a number is a number that when you multiply it by itself you get the first number.

For example:

The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.

The square root of 9 is also -3 since (-3) × (-3) is 9.

The question is asking for the positive and negative square roots of 36.

What number multiplied by itself is 36?

The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36

Answer: 6 or -6
