Answer:
Difference of squares method is a method that is used to evaluate the difference between two perfect squares.
For example, given an algebraic expression in the form:
can be factored as follows:
From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e.
which can be factored as follows:
.
Answer:
3 and 4
Step-by-step explanation:
Consider squares on either side of 15, that is 9 and 16, so
<
<
, that is
3 <
< 4
Answer:
-2x + 5
Step-by-step explanation:
A number cube is rolled 120 times. The number 4 comes up 47 times.
We have to determine the experimental probability of rolling a 4.
The formula to evaluate probability of an event is given by:
Probability = 
So, Probability of rolling a 4 = 
= 
Now, we have to find the theoretical probability of rolling a 4.
Total number of outcomes of number cube = {1,2,3,4,5,6}
Probability of rolling a 4 = 
So, Option B is the correct answer.
Answer:
In a nutshell,
is obtained by applying an horizontal translation on
, followed by a vertical translation.
Step-by-step explanation:
Let be
the parent function,
is obtained by applying an horizontal translation on
, followed by a vertical translation, that is:
(1)
If
, then translation is rightwards.
If
, then translation in downwars.
If
and
, then the resulting function is:
(2)
In a nutshell,
is obtained by applying an horizontal translation on
, followed by a vertical translation.
