$\bf ~\hspace{7em}\textit{rational exponents} \\\\ a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} ~\hspace{10em} a^{-\frac{ n}{ m}} \implies \cfrac{1}{a^{\frac{ n}{ m}}} \implies \cfrac{1}{\sqrt[ m]{a^ n}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \sqrt{13}\implies \sqrt[2]{13^1}\implies 13^{\frac{1}{2}}$

Which expression is equivalent to 14x − 7 + 3(2x − 5)?

skelet666 [1.2K]

Answer:

This equation is equivalent to $20x-22$

$\mathrm{Expand}\:3\left(2x-5\right):\quad 6x-15\\=14x-7+6x-15\\\mathrm{Simplify}\:14x-7+6x-15:\quad 20x-22\\=20x-22$

A black shoe is selected at random from a bin of 6 black shoes and 4 brown shoes and not replaced. What is the probability that

MrMuchimi

Hello,

If 1 black shoe is selected from a bin of 6 black shoes and 4 brown shoes and not replaced, then there are 5 black shoes and 4 brown shoes remaining. To find the probability that the a black shoe will be selected out of 5 black shoes and 4 brown shoes, we divide the number of black shoes over the total number of shoes (Each selection of a shoe is independent).

Doing this, we get 5 / (5+4) = 5/9 ≈ 0.55
The probability that a second shoe selected will be black is 0.55.

Hope this helps!

Please help! Select all that apply. Write the letter of your answer. V = Iwh

Delicious77 [7]

Answer:

Step-by-step explanation:

Formula for volume of a cuboid $= lwh$ . where l is the length, w is the width and h is the height.

Using this equation we can answer the question by using the values given.

$V = (2y+4)(2y-4)(3y) = (4y^2-16)(3y) = 12y^3-48y$

From the list of answers, we can compare each one to the answer we got and see if they match up.

The answers that match up are:

C. $12y^3-48y$ - it is exactly like the answer we got.

D. $3y(4y^2-16) = 12y^3-48y$ - if we simplify the brackets, it is exactly like the answer we got.

E. $(2y+4)(6y^2-12y)=12y^3-24y^2+24y^2-48y=12y^3-48y$ - once again, if we simplify the brackets it is like the answer we got.

None of the other answers are correct as they do not match up with the answer we got.

Use the difference of squares identity to write this polynomial in factored form 9x²-49

Musya8 [376]

$\bf 9x^2-49\implies 3^2x^2-7^2\implies \stackrel{\stackrel{\textit{difference of}}{\textit{squares}}}{(3x)^2-7^2}\implies (3x-7)(3x+7)$
