Answer:

Step-by-step explanation:

when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor).

∴ when volume scale factor = 8

the length scale factor = ∛8 = 2

while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor).

∴ when the length scale factor = 2

the surface area scale factor = 2² = 4

Answer:

3 $\sqrt{2}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplify the given radicals

$\sqrt{50}$

= $\sqrt{25(2)}$

= $\sqrt{25}$ × $\sqrt{2}$

= 5 $\sqrt{2}$

------------------------

$\sqrt{72}$

= $\sqrt{36(2)}$

= $\sqrt{36}$ × $\sqrt{2}$

= 6 $\sqrt{2}$

-----------------------

$\sqrt{128}$

= $\sqrt{64(2)}$

= $\sqrt{64}$ × $\sqrt{2}$

= 8 $\sqrt{2}$

Then

$\sqrt{50}$ + $\sqrt{72}$ - $\sqrt{128}$

= 5 $\sqrt{2}$ + 6 $\sqrt{2}$ - 8 $\sqrt{2}$

= 11 $\sqrt{2}$ - 8 $\sqrt{2}$

= 3 $\sqrt{2}$

Answer:

∠MNP is your answer

Step-by-step explanation:

Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.

Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)

Put them together: ∠MNP is your answer
