Let me explain how you do this
if for 1 day he studies 3/5s of an hour. And the question is asking for 7 days then all we have to do is multiply 3/5s times 7! Ill guide you through the math;)
3   3 7
---- x 7 we can also write it like this --- x ---   lets use this one:)
5   5 1

but now our next step is to multiply across!

<span> 3 7   = 3 x 7 = 21
</span>--- x ---- so our new fraction issssss
5 1 = 5 x 1 = 5

21
-----   and since 5 goes into 21 four times and 2 is left over this is how   5 much he studied in 7 days  4.2 hours
or as a fraction...
1
4 ----
5
answer? 4.2 hours studied :D
have a good one and
MARK ME BRAINLIEST!!:D
thxx bye

M2/n2 is equivalent to _____.

tankabanditka [31]

Answer:

$\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

Step-by-step explanation:

Using exponent rules:

$a^{-n}=\frac{1}{a^n}$

Given the expression:

$\frac{m^2}{n^2}$

⇒ $\frac{m^2}{n^2} = m^2 \cdot \frac{1}{n^2}$

Apply the exponent rule, we have;

$m^2 \cdot n^{-2}$

Therefore, the given expression $\frac{m^2}{n^2}$ is equivalent to $m^2 \cdot n^{-2}$

What are the roots of the quadratic equation below?<br> x2 + 2x= -5

muminat

Answer:

No real root.

Complex roots:

$x = -1 \pm 2i$

Step-by-step explanation:

$x^2 + 2x = -5$

$x^2 + 2x + 5 = 0$

There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x = \dfrac{-2 \pm \sqrt{2^2 - 4(1)(5)}}{2(1)}$

$x = \dfrac{-2 \pm \sqrt{4 - 20}}{2}$

$x = \dfrac{-2 \pm \sqrt{-16}}{2}$

Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.

$x = \dfrac{-2 \pm 4i}{2}$

$x = -1 \pm 2i$
