The perimeter of an equilateral triangle is 24 centimeters. each side of the triangle measures 2.5 centimeters more than the length of each side of a square. the length of each side of the square is centimeters, and the length of each side of the triangle is centimeters. the perimeter of the square is centimeters.

Length of side of square = 5.5cm

Length of side of triangle = 8cm

Perimeter of square = 22cm

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.

what level of math? also i don't need to be paid if i can you.
