Answer:
Option (C) is correct .
Step-by-step explanation:
As the expression given in the question as follows.
Now rationalize the expression.
Using the formula
a² - b² = (a - b) (a + b)
Using in the above
As i² = -1
Option (C) is correct .
=
Multiply both sides by v
<span>
= w Multiply both sides by x
</span>kv = wx Divide both sides by w
<span>
= x Switch the sides to make it easier to read
</span>
x = <span>

Answer:
b > 2
Step-by-step explanation:
- 3b + 8 > 14
- Subtract 8 on both sides
- 3b > 6
- divide by 3 on both sides
- b > 2

Answer:
(5, 1) or maybe (h, k)
Step-by-step explanation:
The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).
In the generic vertex form ...
f(x) = a(x -h)² +k
the letters (h, k) are used to represent the vertex.
__
You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.
