<span>(3x − 4) feet
Solve as a square:
(3x - 4)(3x - 4) = </span><span>9x</span>²<span> − 24x + 16</span>
You have to find out what 15% of $78 dollars is. If you have to do this in your head and not on a calculator you can find 10%, then cut that number in 1/2 and add it to the answer. So 10% of $78 is 7.8 so $7.80. You can divide 7.80 by 2 and get 3.9 and add that to 7.8 which is 11.70. So 15% of $78 is $11.70.
A.) (-2,-4)
(7+3)/2=5, (10+2)/2=6
(-7+5,-10+6)
(-2,-4)
b.)r^2=244
10^2+12^2=244
r=2(61)^(1/2)
c.)(x+2)^2+(y+4)^2=244
2940. To find LCM, listing the multiples may help. Then you will easily be able to view them and circle when you find a common one. :)
