Answer:
a²
Step-by-step explanation:
(see attached for reference)
We can find GCF by expressing each expression into their prime factors
7a² = 7 x a x a
8a³b² = 8 x a x a x a x b x b
by observation, we can see that a x a or a² shows up in both expressions, highlighted in bold here:
7a² = 7 x <em>a x a</em>
8a³b² = 8 x <em>a x a</em> x a x b x b
Hence the greatest common factor is a x a = a²
Answer:
The correct option is D.
Step-by-step explanation:
Domain is the set of all posible
The volume of a rectangular prism is
where,
Dimensions can not be negative. So, the width and volume are always positive.
From the graph it is noticed that
In interval , width and volume is negative, so
interval is not the domain.
In interval (-5,0), width is negative, so (-5,0) interval is not the domain.
In interval (0,3), volume is negative, so (0,3) interval is not the domain.
In interval , width and volume is negative, so
interval is not the domain.
Therefore the correct option is D.
