Monica liga una hoja de papel varias veces y cuenta la cantidad total de rectángulos más pequeños que se forman con los dobleces halla la expresión algebraica que relaciona la cantidad de pliegos en la hoja con la cantidad de rectángulos más pequeños que se forman con ella

(3x-8) or (3x+8)

step-by-step explanation:

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 shoild be o

step-by-step explanation:

x = 3 ± √(5+y)
