Answer:
B.
and
Step-by-step explanation:
The expression given is:

Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are
and
.
Note: The question says
but the option has
.
In case its actually
instead of
, then,
is also a like term and the answer will be D.
Answer:
The volume is 
Step-by-step explanation:
we know that
The volume of a triangular prism is

where
B is the area of the triangular base
L is the length of the prism
we have

----> perpendicular distance between the two triangular bases
substitute

The slop of the line is -10
one point on the line is (3,-6)
10 would be the answer because it is a ijdndnskoskansnsjdjksmskkssksjjsjxhxjdjdnd
