Lisa wants to build a table and put a border around it. the table and border must have an area of 3,996 square inches. the table is 42 inches wide and 36 inches long without the border. which quadratic equation can be used to determine the thickness of the border, x?

The answer is 2,484.

Step-by-step explanation:

First you would have to multiply 42 times 36 then subtract 1,512 from 3,996 you will get 2,484

22

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.
