5 hours x $42 = $210
.5 hours x $42 = $21
$210 + $21 = $231
$231 - $37.95 ( for Materials) = $193.05
The Answer is $193.05
The solution is 10,000,000
0=x^2+29x+100
x= (-b +sqrt(b^2-4ac))/2a x=(-b -sqrt(b^2-4ac))/2a
x=(-(29)+sqrt((29)^2-4(1)(100)))/2(1) x=(-(29)+sqrt((29)^2+4(1)(100)))/2(1)
x=(-29+sqrt441)/2 x=(-29-sqrt441)/2
x=(-29+21)/2 x=(-29-21)/2
x=-8/2 x=-50/2
x= -4 x= -25
Answer:
I think it is this
Rock citizens and overall population of planet Claire is in millions
Step-by-step explanation:
I hope it helped a little, please give me brainliest
Ax²+BC+c=0
x=-b±√b²-4ac/2a
x=-12±√12²-4(-9x4)/2(9)
x=-12±√144+144/18
x=-12±√288/18
x=12±√16
x=-12±4
x=-12-4=-16
x=12+4=8
x=-16;x=8
