Answer:
no solution
Step-by-step explanation:
The discriminant is ...
b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112
A negative discriminant means there are no real solutions to the equation.
_____
The complex solutions are 1±i√7.
If we assume the equation has a typographical error and is intended to be ...
2x^2 -4x -16 = 0
The solutions are x = -2 and x = 4.
Answer:
possible answers below!
Step-by-step explanation:
if they are vertical angles then the measure of ZB is 78
if they are supplementary then ZB is 102 degrees
if they are complementary then ZB is 12 degrees
It depends on where its located, cant really help if i dont have a pic..but i hope this helps! :)

So the equation which will tell the amount of water is</h3><h3>
W= 24 + 32 T</h3>
Step-by-step explanation:
Given,
A water tank already contain 24 gallons of water before the pump was switched to fill it. The pump started 10:00 am and by 10:30 am the tank contained 40 gallons of water . By 1:00 pm the tank contained 120 gallons of water.
The pump filled the tank (40 -24) = 16 gallons in 30 mins.
The pump filled (16 × 2 ) gallons =32 gallons in 1 hour.
So the equation which will tell the amount of water is
W= 24 + 32 T
There isn't enough information for me to help you. Could you attach a picture so that I can see the triangle and where angles B and C are? Thank you.
