Number 1 and number 3 are the same because if you are purchasing three tires that is 75% off the tires you need and one of them you get free. the free one becomes the overall discount of 25% off. number 3 is the same, the one quarter represents 25% off of the purchase.
4.1.....the 4 in the ones place is 10 times bigger then the 4 in the tenths place and 100 times bigger then the 4 in the hundredths place and 1000 times bigger then the 4 in the thousandths place
2.4..the 4 in the tenths place is 10 timed bigger then the 4 in the hundredths place and 100 times bigger then the 4 in the thousandths place
3.14...the 4 in the hundredths place is 10 times bigger then the 4 in the thousandths place
5.124...this 4 in the thousandths place is the smallest
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .

Answer:
-0.53, 2.53 to the nearest hundredth.
Step-by-step explanation:
3x^2 - 6x - 4 = 0
3(x^2 - 2) - 4 = 0
3 [ ( x - 1)^2 - 1] = 4
3(x - 1)^2 - 3 = 4
3(x - 1)^2 = 7
(x - 1)^1 = 7/3
x - 1 = +/- √(7/3)
x = +/- √(7/3) + 1
x = 2.53, -0.53.
