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:
c = 12
Step-by-step explanation:
c = 14 - 2
Answer:
C. y = 2√(x+5) -8
Step-by-step explanation:
Try the offered solutions:
... Selection A is undefined for x < 0.
... Selection B is defined for all x.
... Selection C matches the table values.
... Selection D is undefined for x < 5
If the base is 8cm & the height is 12cm, then you take 8x12, which is 96, and divide it by 2, which would be 48, so the answer is A
