5. Given: L, M, and N are midpo
en: L, M, and N are midpoints of the sides of ATKO.
Find the perimeter of each figure.
a. ATKO
b. ALMK
c. TNML
d. quad. LNOK
6. a. Name all triangles congruent to ATNL.
b. Suppose you are told that the area of ANLM is
17.32 cm? What is the area of ATKO?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

49/6 is going to equal 8 1/6
