What is the quotient 2y^-6y-20/4y+12 ÷ y+5y+6/3y^2+28y+27

malfutka [58]

Answer with explanation:

$\rightarrow \frac{\frac{2y^2-6 y-20}{4 y+12}}{\frac{y^2+5 y+6}{3 y^2+28 y+27}}\\\\\rightarrow \frac{\frac{y^2-3y-10}{2 y+6}}{\frac{(y+2)(y+3)}{3 y^2+28 y+27}}\\\\\rightarrow \frac{\frac{(y-5)(y+2)}{2 (y+3)}}{\frac{(y+2)(y+3)}{3 y^2+28 y+27}}\\\\\rightarrow \frac{(y-5)(y+2)}{2 (y+3)}} \times {\frac{3 y^2+28 y+27}{(y+2)(y+3)}}\\\\ \rightarrow\frac{(y-5)\times(3 y^2+28 y+27)}{2 (y+3)^2}}$

→y²+5y+6

=y²+3 y+2 y+6

=y×(y+3)+2×(y+3)

=(y+2)(y+3)

→y² -3 y-10

=y² -5 y+2 y -10

=y×(y-5)+2×(y-5)

=(y+2)(y-5)

Murljashka [212]

Given:

Oven's temperature rose 3 degrees in $\dfrac{1}{6}$ of a minute.

To find:

How much will the oven heat up in 1 minute at that rate?

Solution:

According to the question,

Oven's temperature rose in $\dfrac{1}{6}$ of a minute $=3 \text{ degrees}$

Oven's temperature rose in 1 minute $=6\times 3 \text{ degrees}$

$=18 \text{ degrees}$

Therefore, the oven's will heat up 18 degrees in 1 minute.

Select the property of equality used to arrive at the conclusion<br> If x= 3, then x2 = 3x

Luda [366]

You used the fact that you can multiply both sides of an equality by the same, non-zero constant.

So, if you start with the trivial equality

$x=x$

you can multiply both sides by 3:

$3x=3x$

But if $x=3$ , $3x$ becomes $3\cdot 3$ , which is $3^2$ . So, we have

$3^2=3\cdot 3$

which leads to

$x^2=3x$

if you recall that $x=3$
