Which of the following are equivalent ratios?<br>A: 12 : 16<br>B: 3 : 5<br>C: 2 : 3<br>D: 6 : 8

Alla [95]

The equivalent ratios are A and D.

Here's an explanation:

When you look at D, you see that 12 is a multiple of 6, and 16 is a multiple of 8. So you know that it looks like they're equivalent. Then you test it out, 12/2=6. 16/2=8. so 12:16 = 6:8. Eyeballing it first can save time sometimes.

GCF: 6x

Step-by-step explanation:

$6x^3-24x^2-72x$

$6x^2x-24xx-72x$

$6x\left(x^2-4x-12\right)$

Common term is $6x$ .

$x^2-4x-12$

$\left(x^2+2x\right)+\left(-6x-12\right)$

$x\left(x+2\right)$

$-6\left(x+2\right)$

$\left(x+2\right)\left(x-6\right)$

^ factors

$6x\left(x+2\right)\left(x-6\right)$
