The figure below is a square with dimensions given. Part A: What is the perimeter of the square in terms of x?
2x - 1 in

Perimeter =

Part B: If the length of each side of the square is doubled, what would be the perimeter of this new square, in terms of x?

Perimeter =

Part C: If x = 5, what would be the ratio of the area of the original square to the area of the new square?

A: 8x-4

B: 16x-8

C: 1:2

step-by-step explanation:

in which figure is point g a centroid

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.
