Answer:
Choice A: x^2−2x+4− 15/x+2
Step-by-step explanation:
15x²+16x+4 =0 (ax² +bx +c=0)
Δ = b²-4ac =256 - 4×15×4 =16
x1 = (-b+√Δ) / 2a = (-16+√16) / 30 =( -16+4) / 30 = -12/30 = - 2/5
x2 = (-b -√Δ) / 2a = (-16 -√16) / 30 = (-16 -4) /30 = -20/30 = -2/3
Answer:
C= 7.6761229314
Step-by-step explanation:
the formula is c=d/p
d= 324.7
p= 42.3
so ... this is how to calculate...
C = 324.7 km/ 42.3 litres
I hope it can help. thanks
