it has four sides and 1 set of parallel lines
First, third, fifth, and sixth answer
600:450 divided by 10 = 60:45
60:45 divided by 15 = 4:3
so 4:3 x 15 = 60:45 x 10 = 600:450
Answer: 1.79
Step-by-step explanation: x2−6x−14=0
For this equation: a=1, b=-6, c=-14
1x2+−6x+−14=0
Step 1: Use quadratic formula with a=1, b=-6, c=-14.
x=
−b±√b2−4ac
2a
x=
−(−6)±√(−6)2−4(1)(−14)
2(1)
x=
6±√92
2
x=3+√23 or x=3−√23
Answer:
x=3+√23 or x=3−√23= 1.79
