Answer:
Step-by-step explanation:
The first step is to determine if some of the terms can be combined (added), so you have to look for like terms (like terms have the same variables with the same exponent).
We have the expression:
We can see that there are two elements that contain x ( and
) , this means that they are like terms and we can add them:
⇒
and this would be the final result, since there are no more like terms in this expression. The answer is D.

Answer:
Venom C is 0.625 times as potent as venom A.
Step-by-step explanation:
We are given that venom A is four times as potent as venom B.
Venom C is 2.5 times as potent as Venom B.
We have to find that how many times as potent is venom C is compared to venom A.
Let Venom B =x
Then Venom A=
Venom C=
Hence, venom C is 0.625 times as potent as venom A.
Given parameters:
Coordinates of the points = (3,4) and (19, 16)
Unknown:
The distance between the points = ?
The midpoint = ?
Solution:
The distance between two points can be mathematically solved using;
D =
where x₁ = 3, x₂ = 19 and y₁ = 4, y₂ = 16
Input the parameters and solve;
D = = 20
Midpoint;
The expression is given as;
x , y
=
,
input the parameters and solve;
= ,
= 11 , 10
The midpoint is (11, 10)
