Hello there!

Goryan [66]

$(x^2+3)^2 + 7x^2+21=-10$

We want to convert this equation in terms of m, where $m = x^2+3$

While solving this problem, I instantly noticed the $x^2+3$ in the first term of the equation. Replace that with m.

$m^2 + 7x^2+21=-10$

Simplifying the rest is not as obvious. Using the distributive property, we can change $[7x^2+21]$ to $[7(x^2+3)]$

Do you see the "m" in here? Look again if you don't.

Now we can simplify the equation to $m^2 + 7m=-10$ and this cannot be simplified further.

I'm always happy to help someone who appreciates the help! :D

What percentage is 28 min of 3 h. <br><br> Plssss explain too!!

Olegator [25]

Answer:

it's 15.5555555556%

Step-by-step explanation:

$28 \: min \: of \: 3h$

$3h \: in \: min = 3 \times 60$

$3h = 180min$

$\frac{28}{180} = \frac{x}{100}$

$(x)180 = 28(100)$

$(x)180 = 2800$

$\frac{(x)180}{180} = \frac{2800}{180}$

$x = \frac{2800}{180}$

$x = 15.5$
