Answer:
8
Step-by-step explanation:
10 + 8 = 18
18 x 2 = 36
2x 2 - 6x = 0 .... if you mean 2x^2 - 6x = 0
then 2x = 0 and x - 3 = 0 << answer
<span>Simplifying
4x2 + 8xy + 4y2
Reorder the terms:
8xy + 4x2 + 4y2
Factor out the Greatest Common Factor (GCF), '4'.
4(2xy + x2 + y2)
Factor a trinomial.
4((x + y)(x + y))
Final result:
4(x + y)(x + y)</span>
Answer:
y = 10
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition x = 4 when y = 15 , then
15 =
( multiply both sides by 4 )
60 = k
y =
← equation of variation
When x = 6 , then
y =
= 10
