10. Infinitely many solutions:
Simplify this equation:
When 
the equation becomes
This equality is true for all x, thus the equation has infinitely many solutions.
11. The equation 
should have one solution x=-1.
First, simplify the equation:
This equation will have solution x=-1 when
Therefore, the initial equation is
12. The equation 
should have infinitely many solutions.
Simplify it:
When 
this equation will have infinitely many solutions.
Answer:
They are very different because hexagons are amazing and squares are boring.
Step-by-step explanation:
3.25(4)+2(6) --plug in values
13+12 --multiply
$25 --answer
Answer: - (2 + 3) = -5
<u>Step-by-step explanation:</u>
When combining numbers that have the same sign, you add them and then include the sign.
For example:
-2 - 3 = -(2 + 3) = -5
-6 - 5 = -(6 + 5) = -11
-7 - 8 = -(7 + 8) = -15
The answer would most commonly be C only because a square is 360 degrees and the surface area would be a 6th of that which is 60 then i multiplied it by 4 because of the four corners signaling the height and or length of the 2D figure square which gives me C.
