Answer:

336

Step-by-step explanation:

The exclamation mark in math represents the factorial operation, which means you multiply the number by decreasing positive integers.

Therefore:

5! = 5 x 4 x 3 x 2 x 1 = 120.

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320

8!/5! = 40320/120

40320/120 = 336

With this equation, all you have to do to solve for a is to divide both sides by 12b and <u>your answer will be $a=\frac{c}{12b}$ </u>

Answer:

1872 cm cubed

Step-by-step explanation:

Volume=Length*Height*Width

We know that the height of the prism is 13 cm.

We also know that the lateral area of the prism is 634 cm squared.

624/4=156

The area of each lateral face is 156 centimeters squared.

The prism's base is a quadrilateral that is regular. This means that the base has equal sides (equilateral) and equal angles (equiangular ).

13x=156

x=12

The base has a side length of 12 cm.

12*13*12=1872

50 POINTS AND MARK BRAINLIEST

Step-by-step explanation:

a) Using the distance formula,

$RS=\sqrt{(2-4)^{2}+(3-4)^{2}}=\sqrt{4+1}=\boxed{\sqrt{5}}\\ST=\sqrt{(4-5)^{2}+(4-0)^{2}}=\sqrt{1+16}=\boxed{\sqrt{17}}\\RT=\sqrt{(2-5)^{2}+(3-0)^{2}}=\sqrt{9+9}=\boxed{3\sqrt{2}}$

b) Using the slope formula,

$m_{\overline{RS}}=\frac{4-3}{4-2}=\boxed{\frac{1}{2}}\\m_{\overline{ST}}=\frac{0-4}{5-4}=\boxed{-4}\\m_{\overline{RT}}=\frac{0-3}{5-2}=\boxed{-1}$

c) The triangle is <em>scalene</em> because each of the sides is of a different length.
