1/10 of 1,700,000 km² is 170,000 km² .
The answer should be. 5x=-12
H(x)=5x+15+4x+20
if x=4, together it would be 5(4)+15+4(4)+20
h(x)=20+15+16+20=71
Divided by 2, they'd each get 35.5
If Frank worked alone, he'd get 5(4)+15= 35
He'd make more working together.
Function: 12+0.5x
12+0.5x=18.5
0.5x=6.5
x=13 days
