Answer:
The independent variable is m (the number of miles driven), and the dependent variable is "e" (the cost)
Step-by-step explanation:
Notice that the cost "depends" upon the number of miles driven, therefore, the cost (identified with the letter "e") is the dependent variable which depends upon the number of miles driven (and which is the independent variable identified with the letter "m")
We will use the substitution:
t = x² ;
t² + 21 x - 100 = 0
t² + 25 t - 4 t - 100 = 0
t ( t + 25 ) - 4 ( t + 25 ) = 0
( t + 25 ) ( t - 4 ) = 0
t 1 = - 25, t 2 = 4
x = √t
Answer:
The roots are:
x 1 = 5 i
x 2 = - 5 i
x 3 = - 2
x 4 = 2

Answer:
Both parallelogram and trapezoid are convex quadrilaterals.
In a parallelogram, both pairs of the opposing sides are parallel while, in a trapezoid, only a pair is parallel.
The diagonals of the parallelogram bisect each other (1:1 ratio) while the diagonals of the trapezoid intersects with a constant ratio between the sections.
Hope this helps have a nice day:) -Jordie-
