Explain how to find the difference -4/5-3/5

1 answer:

8 0

Hello There!

The denominators are already the same therefore you don't need to work on making them the same.
Simply just subtract the numerators:
-4 - 3 = -7
The answer is - 7/5

Hope This Helps You!
Good Luck :)

No. Quincy should have used the trend line to find the corresponding x value when y=80.

How would the expression x^3+64 be rewritten using sum off cubes

Mamont248 [21]

$\bf \textit{difference of cubes}
\\ \quad \\
a^3+b^3 = (a+b)(a^2-ab+b^2)\qquad
(a+b)(a^2-ab+b^2)= a^3+b^3 \\ \quad \\
a^3-b^3 = (a-b)(a^2+ab+b^2)\qquad
(a-b)(a^2+ab+b^2)= a^3-b^3\\\\
-------------------------------\\\\
\boxed{64=4^3}\qquad x^3+64\implies x^3+4^3\implies (x+4)(x^2-x4+4^2)
\\\\\\
(x+4)(x^2-4x+16)$

name three different pairs of fractions that have the same product when multiplied .explain how you got your answer

Deffense [45]

$\frac{5}{10}*\frac{10}{40}=\frac{50}{400}$
$\frac{2}{8}*\frac{2}{4}=\frac{4}{32}$
$\frac{1}{4}*\frac{1}{2}=\frac{1}{8}$

$\frac{1}{8}$ is obtained by multiplying $\frac{1}{2}$ and <span> $\frac{1}{4}$
</span>You basically create equivelant fractions for both 1/2 and 1/4 and multiply by each other. This way you get the same result always.
