Answer:
x²
Step-by-step explanation:
Let "d" represent the divisor (what goes in the blank). Then you have ...
... (x²y)/d = y
Multiplying by d gives ...
... x²y = yd
And dividing by y gives the desired value:
... x² = d
The divisor is x².
Answer:
44
Step-by-step explanation:
substitute k = 1, 2, 3, 4 into 2k² - 4 and sum the terms
k = 1 : 2(1)² - 4 = 2 - 4 = - 2
k = 2 : 2(2)² - 4 = 8 - 4 = 4
k = 3 : 2(3)² - 4 = 18 - 4 = 14
k = 4 : 2(4)² - 4 = 32 - 4 = 28
sum = - 2 + 4 + 14 + 28 = 44
Answer:
True
Step-by-step explanation:
The reciprocal of 
is 
, then
÷ - 
Change ÷ to × and turn the second fraction upside down, that is
× - 
← cancel 11 and 55 by 11
=
