Answer:

It's not a right triangle, there isn't a right angle anywhere there.

Also, it's not applicable via pythagorean theorem

If that is -2+1+4+13 I think it should be 16

Answer:

$36i^{2}+48i+16$

Step-by-step explanation:

$(4+6i)^{2}$ is essentially $(4+6i)(4+6i)$ (you are squaring $(4+6i)$ , so multiplying it by itself), so to simplify, you would need to distribute.

A good way to go about this is using the F.O.I.L. method, multiplying the First numbers in the parentheses, then the Outers, then Inners, and finally, Lasts.

$(4+6i)(4+6i)$ >> $(4+6i)(4+6i)$ >> $(4+6i)(4+6i)$ >> $(4+6i)(4+6i)$

( $(4*4)+(4*6i)+(6i*4)(6i*6i)$ )

After doing so, you would end up with $16+24i+24i+36i^{2}$ , and after combining like terms, $16+48i+36i^{2}$ .

To write the expression in standard form, though, just order the terms from highest to lowest power!

Answer:

Step-by-step explanation:

$\frac{x^3}{a^3} +\frac{a^3}{x^3} =p\\\frac{x^3}{a^3} -\frac{a^3}{x^3} =q\\adding\\2\frac{x^3}{a^3} =p+q\\\frac{x^3}{a^3} =\frac{p+q}{2} \\substitute~in~first\\\frac{p+q}{2} +\frac{2}{p+q} =p\\\frac{(p+q)^2+4}{2(p+q)} =p\\(p+q)^2+4=2p(p+q)\\p^2+q^2+2pq+4-2p^2-2pq=0\\q^2-p^2+4=0\\q^2=p^2-4$

A bakery makes 40 different flavors of muffins. 25% of the flavors have chocolate as one of the ingredients. Draw a tape to show

kobusy [5.1K]

Answer:

10

Step-by-step explanation:

A bakery makes 40 different flavors of muffins.

25% of the flavors have chocolate as one of the ingredients.

Convert 25% to fraction:

$25\%=\dfrac{25}{100}=\dfrac{1}{4}$

So, there are

$40\cdot \dfrac{1}{4}=10$

muffins which have chocolate as one of the ingredients.

In attached tape diagram:

green - with chocolate

blue - without chocolate
