Step-by-step explanation:

(a−2b)

3

\{ - 2 - (2 \times - 12) \}{−2−(2×−12)}

\{ - 2 - ( - 24)\}{−2−(−24)}

\{ - 2 + 24 \}{−2+24}

2222

the required value is 22

let's evaluate :

  • (a - 2b) {}^{3}

  • \{ - 2 - (2 \times  - 12) \}

  • \{  - 2 - ( - 24)\}

  • \{ - 2 + 24 \}

  • 22

the required value is 22

Answer: Yes

Step-by-step explanation:

It is a relation because each person will most likely have a different name and you can have plenty of the same outputs just as long as the input doesn't repeat at all.

What is the completely factored form of x^3 – 64x?
givi [52]
x^3 - 64x \\ \\ gcf = x \\ \\ x( \frac{x^3}{x} +  \frac{-64x}{x} ) \\ \\ x(x^2 - 64) \\ \\ x(x^2 - 8^2) \\ \\ x(x + 8)(x - 8) \\ \\

The final result is: C) x(x - 8)(x + 8).

Verify the following identity:
Paraphin [41]

We will simplify the left hand side of the equation to look like the right

\displaystyle \frac{1-sin(t)}{cos^{2}(t)}  + \frac{1}{1 - sin(t)}

taking the LCM

\displaystyle \frac{[1-sin(t)]^{2} + cos^{2}(t)}{[cos^{2}(t)][1 - sin(t)]}

expanding the binomial in the numerator

\displaystyle \frac{[1 + sin^{2}(t) - 2sin(t) + cos^{2}(t)]}{[cos^{2}(t)][1 - sin(t)]}

Since sin²x + cos²x = 1

\displaystyle \frac{[2 - 2sin(t)]}{[cos^{2}(t)][1 - sin(t)]}

factoring out the 2 from the numerator

\displaystyle \frac{2[1 - sin(t)]}{[cos^{2}(t)][1 - sin(t)]}

1-sin(t) will cancel out

\displaystyle \frac{2}{cos^{2}(t)}

since cos²(t) = 1/(sec²(t))

2 sec^{2}(t)

which is equal to the right hand side of our given equation.

So we verified the identity!
