Answer:
A
Step-by-step explanation:
I just plugged each variable into the equation. A is the only one that works.
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
Step-by-step explanation:
are you sure the fuel consumption is given by 6,8 km/l ?
normally it is given by l/100km.
but ok, let's assume this is correct.
it would mean the car can drive 6,8 km with every liter of fuel in the tank.
how many liters will the car need to go 450 km ?
well, as many liters as 6,8 fits into 450 :
450/6,8 = 66.17647059... liters
this is not a very fuel efficient car ...

Answer:
angle E, the measure is 135
angle J, the measure is 105
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
We are to identify an angle that is supplementary to angle M form the given parallel line.
From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.
If angle m is 45 degrees, then the value of its supplement is 180-45=135
From the second diagram, angle H,angle J and angle P are supplementary to angle M.
If angle M is 75 degrees, the its supplement is 180-75=105
