For what value of k is the expression x^4 + kx^2 + 49 a perfect square?

mote1985 [20]

Answer:

$k=14$

Step-by-step explanation:

Completing the square gives

$x^4 + kx^2 + 49\\= (x^2+7)^2 - 14x^2 + kx^2$

So we have to cancel the latter two terms out for the expression to always become a square (otherwise we are dealing with a square plus something else, which doesn't always result in a square), giving us our answer directly.

Fofino [41]

Answer:

$Raisins : Pretzels = 1 : 2$

$Almonds: Raisins = 3 : 1$

Step-by-step explanation:

Given

$Raisins = 2$

$Pretzels = 4$

$Almonds = 6$

Solving (a):

Ratio of Raisins to Pretzels

$Raisins : Pretzels = 2 : 4$

Divide 2 and 4 by 2

$Raisins : Pretzels = 2/2 : 4/2$

$Raisins : Pretzels = 1 : 2$

Solving (b):

Ratio of Almonds to Raisins

$Almonds: Raisins = 6 : 2$

Divide 2 and 6 by 2

$Almonds: Raisins = 6/2 : 2/2$

$Almonds: Raisins = 3 : 1$
