Answer:
1 and 4 has same pairs of solution.
Step-by-step explanation:
Solutions for the given equations are:
\begin{gathered}1. (x+6)(x - 6) = 0\\(x+6) = 0, (x-6) = 0\\x = -6, x = 6\\\\2. (x + 6)(x + 6) = 0\\(x+6) = 0, (x+6) = 0\\x = -6, x = -6\\\\3. (x - 6)(x - 6) = 0\\(x-6) = 0, (x-6) = 0\\x = 6, x = 6\\\\4. (2x + 12)(2x - 12) = 0\\(2x+12) = 0, (2x-12) = 0\\x = -6, x = 6\\\\5. (2x - 12)(x - 12) = 0\\(2x-12) = 0, (x-12) = 0\\x = 6, x = 12\\\\6. (x+12)(x - 12) = 0\\(x+12) = 0, (x-12) = 0\\x = -12, x = 12\\\\7. (x +12)(x-6) = 0\\(x+12) = 0, (x-6) = 0\\x = -12, x = 6\end{gathered}
1.(x+6)(x−6)=0
(x+6)=0,(x−6)=0
x=−6,x=6
2.(x+6)(x+6)=0
(x+6)=0,(x+6)=0
x=−6,x=−6
3.(x−6)(x−6)=0
(x−6)=0,(x−6)=0
x=6,x=6
4.(2x+12)(2x−12)=0
(2x+12)=0,(2x−12)=0
x=−6,x=6
5.(2x−12)(x−12)=0
(2x−12)=0,(x−12)=0
x=6,x=12
6.(x+12)(x−12)=0
(x+12)=0,(x−12)=0
x=−12,x=12
7.(x+12)(x−6)=0
(x+12)=0,(x−6)=0
x=−12,x=6
(x+6)(x - 6) = 0 and (2x + 12)(2x - 12) = 0 have same pair of solutions.

Answer:
4, 3, 4
Step-by-step explanation:
The unsimplified ratio of squares to triangles is 6:8, which simplifies to 3:4. That means, for every 3 squares, there are 4 triangles
As stated above, the simplified ratio of squares to triangles is 3:4
The answer is "She Made $13"
Start a $0 then add/subtract her profit/loss.
0-3+4-3+6-2+5-6+12=13
Providing 1 mile is 5280 feet, then,
![v=63 miles/s=63\times5280 feet/s=332640\ \ \ \ feet/s](https://tex.z-dn.net/?f=v%3D63%20miles%2Fs%3D63%5Ctimes5280%20feet%2Fs%3D332640%5C%20%5C%20%5C%20%5C%20feet%2Fs)
It will travel,
![space=v\cdot t=332640\cdot 15/3600=1386\ \ \ feet](https://tex.z-dn.net/?f=space%3Dv%5Ccdot%20t%3D332640%5Ccdot%2015%2F3600%3D1386%5C%20%5C%20%5C%20feet)
in 15 seconds.
Answer:
3.803% Profit
Step-by-step explanation:
First let us calculate total sales, then calculate the total cost, and then divide the two.
Sale: 120*1.1=132 and 52*.9=46.8
Cost: 120 and 52
Profit equation:
![\frac{Net sales-COGS}{Net Sales} =Profit](https://tex.z-dn.net/?f=%5Cfrac%7BNet%20sales-COGS%7D%7BNet%20Sales%7D%20%3DProfit)
![\frac{(132+46.8)-(120+52)}{(132+46.8)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28132%2B46.8%29-%28120%2B52%29%7D%7B%28132%2B46.8%29%7D)
Simplify:
or 3.803% Profit
