(y+8)/(y^2+7)=(?)/(y^2+7)(y-8)

yawa3891 [41]

Answer:

$y^{2} - 64$

Step-by-step explanation:

$\frac{y+8}{y^{2} + 7 } = \frac{k}{(y^{2} + 7) (y-8) }$

This gives x= $y^{2} - 64$

Using the formula that $x^{2} - y^{2} = (x+y)(x-y)$

Joy makes 6.5 litres of soup, correct to the nearest 0.5 litre. She serves the soup in 280 ml portions, correct to the nearest 1

Kazeer [188]

Answer:

Joy has not enough soup

Explanation:

If Joy is serving correct to nearest 10 with 280 ml maximum.

Maximum soup served by her in one turn = 290 ml

Number of people she is serving = 22

Amount of soup required = 22 x 0.29 = 6380 ml = 6.38 L

Amount of soup she has = 6.5-0.5 L=6 L

Amount of soup she has < Amount of soup required

So, Joy has not enough soup.

Factor completely 3X^2 -25

Dominik [7]

In order to factor a polynomial, you have to find its roots

$x_1,\ x_2,\ldots,x_n$

So that you can factor it as

$p(x)=(x-x_1)(x-x_2)\cdots(x-x_n)$

So, in this case, we're looking for the solutions of

$3x^2-25=0 \iff 3x^2=25 \iff x^2 = \dfrac{25}{3} \iff x=\pm\sqrt{\dfrac{25}{3}}=\pm\dfrac{5}{\sqrt{3}}$

So, the polynomial can be written as

$3x^2-25 = \left(x-\dfrac{5}{\sqrt{3}}\right)\left(x+\dfrac{5}{\sqrt{3}}\right)$
