Answer:

sqrt(ac)

±---------- = b

Step-by-step explanation:

a= 9b^2 c

Divide each side by 9c

a/9c = 9b^2c / 9c

a/9c= b^2

Take the sqrt of each side

±sqrt(a/9c) = sqt(b^2)

Remember that sqrt (xy) = sqrt(x) sqrt(y)

±sqrt(a/c) * 1/ sqrt(9) = b

±sqrt(a) 1

--------- * ------ = b

sqrt(c) 3

Multiply by sqrt(c)/ sqrt(c)

±sqrt(a) sqrt(c)

--------- * ----------- = b

sqrt(c) 3sqrt(c)

±sqrt(ac)

---------- = b

If the volume of the solid below is 84 cubic inches, what is the height of the solid?

frozen [14]

Height = Volume / area of base

Area of base = 3.5 x 4 = 14 sq. inches.

Height = 84 / 14

Height = 6 inches.

Find the length of the missing side. The triangle is not drawn to scale.

dexar [7]

There are two ways you can go about this. If you know the 3-4-5 triangle, and you multiply by 3, you will get a 6-8-10 triangle, so the missing length is 6. You can also simply us the pythagorean theorem. $a^2+(8)^2=(10)^2\\a^2+64=100\\a^2=36\\a=6$
