Please explain this, I have no idea how to do it! t2 = 81
What does T stand for? Round to the nearest tenth if necessary.

t=40.5

Step-by-step explanation:

T likely stands for time. but I suspect you haven't given us the full question because the piece you gave us doesn't determine what T stands for. either way, t is your variable. could be substituted for x or any other variable.

t2=81

isolate t

/2

t= 81/2

t= 40.5

t = 9

Step-by-step explanation:

t² = 81

√t² = √81

t = 9

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
