Answer:
The answer is 4r² – 9
Denise answer is correct.
Step-by-step explanation:
One of the methods of solving the given equation [(2r – 3)(2r + 3)] is the FOIL method
Using the FOIL method (Used for multiplying binomials)
F stands for first
O stands for outer
I stands for inner
L stands for last
In this method, it means we will first multiply the first terms followed by multiplying the outer term, then multiplying the inner terms and finally, the last terms.
So, for the equation (2r – 3)(2r + 3)
First : (2r)(2r) = 4r²
Outer : (2r)(+3) = 6r
Inner : (–3)(2r) = – 6r
Last : (–3)(+3) = – 9
Adding the results we get
4r² + 6r – 6r – 9 (+6r and – 6r cancels out)
= 4r² – 9
∴ (2r – 3)(2r + 3) = 4r² – 9
Hence, Denise answer is correct
Answer:

Step-by-step explanation:





Apply the difference of two squares formula.



Answer:
Step-by-step explanation:
combo 1 : 3 cheese and 1 pepperoni
combo 2: 2 cheese and 2 pepperoni
combo 3: 1 cheese and 3 pepperoni
he chooses :
5 combo 1's : so thats (5 * 3) = 15 cheese, (5 * 1) = 5 pepperoni
2 combo 2's.....(2*2) = 4 cheese and (2 * 2) = 4 pepperoni
3 combo 3's....3(3 * 1) = 3 cheese and (3 * 3) = 9 pepperoni
added = a total of 22 cheese and 18 pepperoni....thats 40 pizzas
so the probability that he will randomly pick a pepperoni is 18/40 which reduces to 9/20
the probability that he will pick a cheese is 22/40 which reduces to 11/20
so ur answer is D. <===
