I think this is the answer ( −∞,∞)
Answer:
226.8cm^2
Step-by-step explanation:
A=pir^2
24/4 = 6 (radius of small circles)
pi6^2= 113.097335529 times 2 (because theres 2 of them)
=226.8
24/2 = 12 (radius of big circle)
pi12^2= 452.4 minus 226.8 (to get the leftover space)
=226.8
Answer:
40
Step-by-step explanation:
Answer:
8x(10)^9 - 2 x (10)^1
1x(10)^3 - 9 x (10)^2
Step-by-step explanation:
3.1 X (10)^4- 6.5 X (10)^2
= 31000- 650
= 30,350
For greater number
_x10^blank - _ x 10^_
8x(10)^9 - 2 x (10)^1 ( we use 9 as the power because greater number used as power gives the bigger number and the next smaller number 8 as base. Similarly we use smaller number for power to get a smaller for the greatest difference)
= 8,000,000,000 -20
= 7,999,999,980
For smaller number
_x10^blank - _ x 10^_
1x(10)^3 - 9 x (10)^2 ( we use 3 as the power because smaller number used as power gives the smaller number and the next smallest number 1 as base. Similarly we use next smaller number for power to get the next smaller for the smallest difference)
= 1000- 900
= 100
We fill in the blanks keeping in mind that we do not have to repeat the numbers from 1-9 and also the numbers should have such an arrangement that they show the smallest and largest possible differences.
Answer:4((x+3)(x-1))
Step-by-step explanation:
Factorize the common terms
4(x^2+2x-3)
Factorize
X^2+2x-3=(x+3)(x-1)
(X+3)(x-1)
4((x+3)(x-1))
