Question

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

Answer 1

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

Answer 2

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

Answer 3

just multiply all the coordinates by the scale factor: 2

V' = (12,4)
and so on

Answer 4

I think the Coordinates need to be doubled.

Answer 5

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

Answer 6

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

Answer 7

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.

Answer 8

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.

Answer 9

She is right

Answer 10

wait who is right

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

Answer 25

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

.

Answer 27

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.
