You can do (380/4) + (380*1)
Or use a calculator.
The answer is 475
(6 Cosx)2
1 x 49, 7 x 7
380 x 2 = 760
x2+x-380 = (x+20)(x-19) when factored
If 38,000 is 100% then 380 is 1% and 380 x 80 is 80% .... 380 x 80 = 30,400
2 x 5 x 5 = 50
(6 Cosx)2
1 x 49, 7 x 7
380 x 2 = 760
1 x 380, 2 x 190, 4 x 95, 5 x 76, 10 x 38, 19 x 20.
x2 + x = 380 x2 + x - 380 = 0 (x + 20)(x - 19) x = 19, -20
98 = 1 x 98, 2 x 49, 7 x 14.
x2+x-380 = (x+20)(x-19) when factored
If 38,000 is 100% then 380 is 1% and 380 x 80 is 80% .... 380 x 80 = 30,400
$75-$125, depending on condition.
760
1 x 125, 5 x 25 = 125
