Answer:
Step-by-step explanation:
36+88+y=180
124+y=180
y=180-124
<u>y=56</u>
x+90+56=180
x+146=180
x=180-146
<u>x=34</u>

In the first day she drive by her self 300
The miles remains to the second day
582-300=282
In the second day it will share the driving with her cousin equally
so she will drive 282/2=141 miles and her cousin also 141 miles
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).
