Step-by-step explanation:
We should find the area of the carpet squares. Since each side is 1 foot, the area will be 1. Now, Julie used 120 carpet squares, which is 1 in area. So, we will have to multiply 1 by 120.
120×1=120
The area of the floor is 120 ft².
Answer:
The required biconditional statement is: You pay the Durham poll tax if and only if you are 18 or old.
Step-by-step explanation:
In the provided statement,
The statement is: If you pay the Durham poll tax, then you are 18 years or older.
The converse is: If you are 18 years or older, then you pay the Durham poll tax.
The combination of a conditional statement and its converse is called biconditional statement.
The biconditional statement contains if and only if phrase between two part of the statement.
Which means the statement and converse both are true.
Therefore, the required biconditional statement is: You pay the Durham poll tax if and only if you are 18 or old.
Answer:
![x_1=-\frac{b}a,x_2=-\frac{d}c](https://tex.z-dn.net/?f=x_1%3D-%5Cfrac%7Bb%7Da%2Cx_2%3D-%5Cfrac%7Bd%7Dc)
Step-by-step explanation:
Solving for x:
![ax(cx + d) =-b(cx +d)\\ax(cx + d)+b(cx+d)=0\\(ax+b)(cx+d)=0](https://tex.z-dn.net/?f=ax%28cx%20%2B%20d%29%20%3D-b%28cx%20%2Bd%29%5C%5Cax%28cx%20%2B%20d%29%2Bb%28cx%2Bd%29%3D0%5C%5C%28ax%2Bb%29%28cx%2Bd%29%3D0)
In this form is easy to identify the factors of the quadratic function:
. The two solutions are the values that make each of the factors equals to zero.
![ax_1+b=0\\ax_1=-b\\x_1=-\frac{b}a\\cx_2+d=0\\cx_2=-d\\x_2=-\frac{d}c](https://tex.z-dn.net/?f=ax_1%2Bb%3D0%5C%5Cax_1%3D-b%5C%5Cx_1%3D-%5Cfrac%7Bb%7Da%5C%5Ccx_2%2Bd%3D0%5C%5Ccx_2%3D-d%5C%5Cx_2%3D-%5Cfrac%7Bd%7Dc)
