The two longest sides of a pentagon are each 3 times as long as the shortest side. the other sides are each 8 meters longer than the shortest side. find the length of each side of the perimeter is 79 meters.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

what is the original number? you forgot to add it.

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.

a - base

b - exponent

so,
