The points on the number line are -6 and 2.

2 - -6 = 4

2 + 6 = 4

A is not the answer.

--6 - 2 = 8

+6 - 2 = 4

B may be the answer.

-6 - 2 = -8

C is not the answer.

-2 - -6 = 4

-2 + 6 = 4

D is not the answer.

<h3>The answer is B) The value of -a - 6 is positive.</h3>

Let me know if this is the correct answer. :)

Find the volume of a trough 5 meters long whose ends are equilateral triangles, each of whose

yawa3891 [41]

Answer:

$V=5\sqrt{3}\ m^3$

Step-by-step explanation:

we know that

The volume of a trough is equal to

$V=BL$

where

B is the area of equilateral triangle

L is the length of a trough

step 1

Find the area of equilateral triangle B

The area of a equilateral triangle applying the law of sines is equal to

$B=\frac{1}{2} b^{2} sin(60\°)$

where

$b=2\ m$

$sin(60\°)=\frac{\sqrt{3}}{2}$

substitute

$B=\frac{1}{2}(2)^{2} (\frac{\sqrt{3}}{2})$

$B=\sqrt{3}\ m^{2}$

step 2

Find the volume of a trough

$V=BL$

we have

$B=\sqrt{3}\ m^{2}$

$L=5\ m$

substitute

$V=(\sqrt{3})(5)$

$V=5\sqrt{3}\ m^3$
