WHICH EXPRESSION IS NOT EQUIVALENT?
s344n2d4d5 [400]

Answer:

C

Step-by-step explanation:

First, factor the original expression:

2x^2+10x+12\\2(x^2+5x+6)\\2(x+3)(x+2)

As we can see, D is the same as above. Eliminate D.

Go through each of the answer choices.

A:

(2x+4)(x+3)\\=2(x+2)(x+3)

This is equivalent to what we factored. Eliminate A.

B:

(2x+6)(x+2)\\=2(x+3)(x+2)

This is again equivalent to what we factored. Eliminate B.

C:

(2x+3)(x+4)\\

This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.

1. The formula for the volume of a cone is
Andre45 [30]

Answer:

r=\sqrt{\frac{3V}{\pi\ h}}

Step-by-step explanation:

The volume of cone is given by:

V=\frac{1}{3}\pi\ r^2\ h

where r is the radius of the base and h is the height of the cone.

We need to solve for r

we have V=\frac{1}{3}\ \pi\ r^2\ h

Multiplying both sides by 3 to remove \frac{1}{3}

⇒ 3\times V=3\times \frac{1}{3}\ \pi\ r^2\ h

⇒ 3V=\pi\ r^2\ h

dividing both sides by \pi\ h

⇒ \frac{3V}{\pi\ h}=\frac{\pi r^2 h}{\pi\ h}

⇒ \frac{3V}{\pi\ h}=r^2

Taking square root both sides:

⇒ \sqrt{\frac{3V}{\pi\ h}}=\sqrt{r^2}

⇒ \sqrt{\frac{3V}{\pi\ h}}=r

∴ r=\sqrt{\frac{3V}{\pi\ h}}
