Answer:

x = ± 2 $\sqrt{6}$

Step-by-step explanation:

x² + 1 = 25 ( subtract 1 from both sides )

x² = 24 ( take square root of both sides )

x = ± $\sqrt{24}$ = ± $\sqrt{4(6)}$ = $\sqrt{4}$ × $\sqrt{6}$ = ± 2 $\sqrt{6}$

x = - 2 $\sqrt{6}$ , x = 2 $\sqrt{6}$

The ratio between the square of a number and it's cube is 1:3 what is the number

Dimas [21]

Answer:

Step-by-step explanation:

Call that number “x”

The square of that number is x^2

Also as the cube is x^3

The ratio between these 2 values is 1:3, this means x^2 / x^3 = 1 / 3

<==> 1 / x = 1 / 3 (eliminate “x^2” for numerator and denominator of the fraction x^2 / x^3 )

<==> x = 1 * 3 / 1 = 3

So, that number is 3 ! This math problem seems simple ;)

A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 40% off clearan

Hatshy [7]

Answer: He would pay 45% of the original price.

Step-by-step explanation:

Since we have given that

Let the original price of item be 'x'

Rate mark down by 25%

Amount of marked down would be

$\dfrac{25}{100}\times x\\\\=0.25x$

Amount after marked down becomes

$x-0.25x\\\\=0.75x$

Additional clearance items by 40% off

Amount of additional off is given by

$\dfrac{40}{100}\times 0.75x\\\\=0.4\times 0.75x\\\\=0.3x$

After additional off, the amount becomes,

$0.75x-0.3x\\\\=0.45x$

Hence, he would pay 45% of the original price.
