Gerald purchased a rectangular plot of land. The length of the plot is 20 feet more than the width. The cost of the land was $12 per square foot. Gerald also had a fence put around the entire perimeter of the plot, at a cost of S8 per linear foot. The total amount he spent on both the land and the fence was $10,560. Part A Write an equation in two variables for the perimeter, P, and an equation in two variables for the area, A, of the plot of land where x is the width of the plot in feet. Provide evidence to support your equations

P =2(20X +X) and A = 20X + X or 1/2P

Step-by-step explanation:

to find the perimeter u most do 2(L*W) withe the width being x and the length being 20 * x then to find the Area  its just L*W or if u want to look good do 1/2P or the perimeter

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.
