Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
I am 100% positive it is 0 and 5
Answer:
The last option
Step-by-step explanation:
This definitely isn't a parallelogram, so you can knock both of the yes answers out. One of the rules of parallelograms are that if there is 1 right angle then all four need to be right angles, even if the others are supplementary if the right angle rule is not followed then the shape is not a parallelogram.
Answer:
120000 cm
Step-by-step explanation:
1 km = 1000 m
1 m = 100 cm
1.2 km * 1000m/ 1km * 100 cm /1 m = 1.2 * 1000 * 100 cm = 120000 cm
