Circumference is 2*pi*r
2 * 3.142 * 11.2 = 70.3808, to 1 decimal place is 70.4cm^2
The answer is 0.079
*Remove percent sign
*Move decimal back 2 times
x=1001+75.55x
Simplify
x=<span><span>75.55x</span>+1001</span>
Subtract
x−<span>75.55x</span>=<span><span><span>75.55x</span>+1001</span>−<span>75.55x</span></span>
−<span>74.55x</span>=1001
Divide
<span><span>−<span>74.55x/</span></span><span>−74.55 = </span></span>

Answer: the system has no solution
Step-by-step explanation: for a solution to occur the lines have to cross
We can solve this using the FOIL method.
= (7x + 3)(7x - 3)
= (7x * 7x) + (7x * -3) + (3 * 7x) + (3 * -3)
= 49x - 21x + 21x - 9
= 49x - 9
Hope This Helped! Good Luck!
