For an expression to have a rational equivalent when solved, the denominator should not be equal to 0. If the denominator is equal to zero, the expression becomes indefinite or undetermined. This is the reason for the restriction of the use of x being equal to 3 or -10.
In the given above, we can see that the expression x-3 appears both in the numerator and denominator. Hence, this can be cancelled. We are then left with the expression,
(x + 5) / (x + 10)
Therefore, the answer to this item is letter C.
Answer:
4
Step-by-step explanation:
2N - 3 = 5
2N = 5 +3 = 8
N = 8/2 = 4
100=1,478,300
1000=1,478,000
10,000=1,470,000
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
If you want 3/4 in 64's, multiply the numerator (3) by 16, as 4 x 16 = 64.
<span>3 x 16 </span>
<span>--------- </span>
<span>4 x 16 </span>
<span>= 48/64</span>
