Answer:
B: The hypothesis is revised and another experiment is conducted.
Step-by-step explanation:
If several different experiments all reveal that the hypothesis has not been confirmed, a revision of the hypothesis is in order. Perhaps it was the hypothesis all along that needed amendment.
We have to find the quotient :
( 4 x³ y + 12 x² y³ - 20 x y ) / ( 4 x y ) =
= 4 x y ( x² + 3 x y² - 5 ) / ( 4 x y ) = ( Then 4 x y will be cancelled )
= x² + 3 x y² - 5
Answer:
D ) x² + 3 x y² - 5
Answer: should be
-3x^2+4x
Step-by-step explanation: combining like terms
Answer:
D
Step-by-step explanation:
plug in the value to the given expression
f(-4) = 4(-4) - 9
f(-4) = -16 - 9
f(-4) = -25
