Answer:
the answer is 7
Step-by-step explanation:
22-8 is 14
-7 - (-9) is 2
14/2 is 7
The model (x+a)(x-a) will represents the factors of 4x²-9 as (2x+3)(2x-3).
<h3>What are the quadratic equations in one variable completing the squares method?</h3>
The "completing the squares" method aims to construct a quadratic equation of the form where the x variable is entirely covered by a single squared term, which is the square of a linear expression in x, as the name suggests.
The quadratic equation can resemble this:
x²-a² = (x+a)(x-a)
Given equation;
⇒4x²-9
⇒(2x)²-3²
The equation can be modeled as;
(2x+3)(2x-3)
Hence the model (x+a)(x-b) will represents the factors of 4x²-9 as (2x+3)(2x-3).

A gets 5 parts and I gets 8 parts
So 5+8=13. A will get 5/13 parts of the total
5/13*32(total)=12.3 since he can’t get .3 we round and Amir gets 12 leaving 20 for Isaac.
Answer:
$621
Step-by-step explanation:
-Profit is the net amount after deducting the total expenses from the sales revenue realized.
-Wally's expenses are:
-Wally's sales revenue is:
The profit made is therefore calculated as:
Hence, Wally's profit last year was $621
