Answer: $y^4$ + $\frac{-73}{35}y^2$ - $2$

Step-by-step explanation:

Use FOIL:

$y^4$ + $\frac{-14}{5}y^2$ + $\frac{5}{7}y^2$ + $\frac{-70}{35}$

Make $\frac{-14}{5}y^2$ and $\frac{5}{7}y^2$ have the same numerator:

$\frac{-14*7}{5*7}y^2 =\frac{-98}{35}y^2$

$\frac{5*5}{7*5} y^2=\frac{25}{35} y^2$

Then add like terms and simplify:

$y^4$ + $\frac{-98}{35}y^2$ + $\frac{25}{35} y^2$ + $\frac{-70}{35}$

$y^4$ + $\frac{-73}{35}y^2$ - $2$

Help quick please. Order the numbers from least to greatest.

Anastasy [175]

Answer:

$-2\frac{1}{4}$

Step-by-step explanation:

Mod of any number represents the absolute value of the number.

Therefore, $|-2\frac{1}{4}|=2\frac{1}{4}$ = 2.25

$-2\frac{1}{4}=-2.25$

$|1\frac{1}{4}|=1.25$

$\frac{3}{4}=0.75$

$|-1\frac{3}{4}|=1\frac{3}{4}=1.75$

$-1\frac{1}{4}=-1.25$

Now we can arrange these numbers in ascending order.

-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25

Therefore, $-2\frac{1}{4}$
