maks197457 [2]

Answer and Step-by-step explanation:

The answer would be the last answer choice.

$(n^{-3} )^{6}$

Exponents that are the being raised by another exponent get multiplied, so 6 times -3 is -18.

What is the value of x using the Pythagorean theorem?

Vesnalui [34]

A^2+b^2= c^2

Plug in the points. the longest side is always c.

95.2^2+ b^2= 168^2.

Square the numbers.

9063.04+ b^2= 28224

Subtract 9063.04 on both sides.

b^2= 19160.96

Find the square root.

b= 138.423119456

Or, b= 138.4 (rounded down)

I hope this helps!

Kazeer [188]

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

$\frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5$
