<h3>
Answer: D) 5</h3>
=======================================================
Explanation:
If we plugged x = 3 into the expression, then we'd get x-3 = 3-3 = 0 in the denominator. That's not allowed. But we can simplify first
x^2-x-6 factors to (x-3)(x+2). The key here is that (x-3) is a factor. It cancels with the x-3 in the denominator
So, 
Allowing us to say,
No because it doesn't make sense <span />
Answer:
the rational numbers that doesn’t have a reciprocal are [math]0 [/math] (which can also be expressed as [math]\frac {0} {x}, x \neq 0 [/math] ), and any number of the form [math]\frac {x} {0} [/math].
Step-by-step explanation:
Answer:
5, -9
Step-by-step explanation:
(x - 5)(x + 9) = 0 These are factors, to get the roots, just set each one equal to zero
x - 5 = 0
x = 5
x + 9 = 0
x = -9
Let
<span>p ----------------> is the perimeter of the base
</span><span>h ---------------> is the height
</span><span>BA-------------> is the area of the bases
</span><span>LA--------------> is the lateral area
we know that surface area is </span><span>the sum of base areas plus lateral areas
</span><span>then
SA=[BA]+P*h
but remember that
LA=P*h
then
SA=</span>[BA]+LA----------> SA=BA+LA
the answer are the options B.) SA=BA+LA and the option D.) SA=BA+ph
