Use cross products to demonstrate whether the two ratios are equivalent: four-sixths and fourteen over twenty-one

4/6 = 14/21
4*21 = 6*14
yes

Thanks dude! could you help me with this one and then that's it.

Find the coordinates of quadrilateral V' W' X' Y' after a dilation with the scale factor of 2.
Original coordinates:

V(6, 2), W(–2, 4), X(–3, –2), Y(3, –5), scale factor of 2

just multiply all the coordinates by the scale factor: 2

V' = (12,4)
and so on

I think the Coordinates need to be doubled.

btw I just gave you the wrong answer for the coordinates question.

no you gave the right ones...thanks!!!

reduce all fractions to lowest terms and compare them:

4/6 can be reduced to 2/3

14/21 can be reduced to 2/3

The ratios are equivalent.

the ratios aren't equivalent. if you do cross products they would turn into 4/21=6/14 yes, 4 and 14 can cross and turn into 2 and 7 but 6 and 21 can't simplify therefore they are not equivalent.

She is right

wait who is right

2OI9!!!
oh, how I miss you!!
2O2O decided to show up and ruin the world. Man in fact 2O2O is almost gone! 2O2I is on its way! hopefully, things will be better then. But who knows. Anyways we miss you 2OI9!! Not to offend 2O2O but you were better than 2O2O. Like wayyy better
(okay dont mind me having a conversation with a year.. specifically 2019)

Just gonna say Im is right, the other person is wrong, but also haha, ya 2020 sucksssssssssssssssss, like ngl I miss 2019 and years like 2016 and all that, I hope this year ends quicker.

I miss every other year before 2020. 2020 needs to just go away! Hopefully 2021 will be a better year for this world!

@UwU same!! but i have a feeling it's only going to get worse :((

A wave of coronavirus will hit harder than 2020's coronavirus hit----------sincerly
2021

Sincerely
2021

Hey, uh. What's does " * " mean?

"*" means to multiply.

R.I.P. The 90s
You were the best part of the year.
Bc you didnt have a pandemic.

Are the ratios 4:5 and 14:20 equivalent?

Yes

2020 is best year

Anyone like my post if they hate math like I do and would rather play video games!

i could be playing minecraft, but noooo i have to do schoolwork

so whats the answer to this problem?
Use cross products to demonstrate whether the two ratios are equivalent:
4/6
and
14/21
.

Good Bye 2020 :(

Hey, to 2022, i hate to be here, but this happens anyway, maybe if i was in school i wouldn't be doing this. And thanks to what happened in 2021, because that's why i'm here suffering anyway, i really miss u 2020 but now it is about to be 2023 in a month so i'm saying an early hey to 2023.
