Triangle tuv and the triangle lmn are similar what is the measure of side lm

The answer should be 28

28 cm

Step-by-step explanation:

We can write a similarity statement to help us:

TUV ~ LMN

TU corresponds to LM; this gives us the ratio

8/x

TV corresponds to LN; this gives us the ratio

6/21

Together, they give us the proportion

8/x = 6/21

Cross multiplying, we have

8(21) = x(6)

168 = 6x

Divide both sides by 6:

168/6 = 6x/6

28 = x

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
