Answer:
(x - 6)(x + 4)
Step-by-step explanation:
x^2 -2x-24
-24 = -6 * 4
- 6 + 4 = -2
So
x^2 -2x-24 = (x - 6)(x + 4)
Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = 
= 
= 17
Noe find the mean of 25 and 17 and 17 and 9
mean = 
= 
= 21 and
mean = 
= 
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
(8)=ones place
(1)0=tens place
(1)00=hundreds place
(9)000=thousands place
The "1" beside the 8, is the tenths spot so you would round that part of the number.
Therefore the answer would be:
9120
In order to find this you need to assume that they are declared as X and as X + 2. This makes the formula for calculating it x (x+2)=483, and this, based on the formulas for calculation, equals
x^2+2x-83=0
From this we can see that a negative X is -23, which when +2 is added results in -21.
