Answer:
D.
Step-by-step explanation:
Area=w*h
w*h=(2h)*(h)=2h^2
dA/dt=2(2h)=4h
dA/dt=4h dh/dt in^2/sec
In standard form, it would be 0.000000146
In order to get who was right we need to solve the expression:
2a^2b(-2ab^3)^-2
The above can be written as fraction to get:
(2a^2b)/(-2ab^3)^2
=(2a^2b)/(4a^2b^6)
=1/2(a^(2-2)b^(1-6))
=1/2a^0b^-5
=1/2b^(-5)
This implies that neither of the was right
Answer:
you're right, a=1 b=7 c=19

Answer:
Not Sure
Step-by-step explanation: I dont know the anwser but I can try to help, all I know is the the measure of angle EDF is supplementery to angle EDG so I hope that helps. In other words, 180-21x+5 = measure of angle EDF.
