Answer:
B
Step-by-step explanation:
The explicit rule for a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 64 and r =
=
= 2 , then
= 64
→ B
Answer:
60in
Step-by-step explanation:
Given data
Length= 24 in
Width = 18 in
Diagonally, we need to find using the Pythagoras theorem
D^2= L^2+W^2
D^2= 24^2+18^2
D^2= 576+324
D^2= 900
Square both sides
D= √900
D= 30 in
For both sides
=30*2= 60in
Answer:
a difference of squares
Step-by-step explanation:
Let's write down the expression:

we can see that this expression is one of the form
which is the general expression of a difference of squares.
To be more specific and to see why we say this, let's make
and 
Now, if we substitute this in the general formula, we get:

Thus, this expression is a difference of squares.
