A store allows customers to fill their own bags of candy. Terri decides she only wants jelly beans and chocolate drops. Jelly be
NISA [10]
Jelly beans - $0.98 per pound
chocolate drops - $0.67 per pounds
Terri's bag = 2.1 pounds and $1.56

p = represents the pounds jelly beans.
c = represents the pounds in chocolate drops

p + c  = 2.1
0.98p + 0.67c = 1.56

c = 2.1 - p  ; number of pounds of chocolate drops

0.98p + 0.67(2.1 - p) = 1.56
0.98p + 1.41 - 0.67p = 1.56
0.98p - 0.67p = 1.56 - 1.41
0.31p = 0.15
p = 0.15/0.31
p = 0.48 pounds of jelly beans

c = 2.1 - 0.48
c = 1.62 pounds of chocolate drops.

Which expression is prime? A) x2 - 6x + 9 B) x2 + 16x + 64 C) 4x2 + 20x + 25 D) 9x2 - 30x - 25
dlinn [17]
D is a prime polynomial. 

The best way to figure this out is by attempting to factor them all. Each of them factors into perfect squares except for D. 

A)
x^2 - 6x + 9 = (x - 3)^2

B) 
x^2 + 16x + 64 = (x + 8)^2

C)
4x^2 + 20x + 25 = (2x + 5)^2

D we can also tell won't have a perfect square like that because it ends in a negative number. No number multiplied by itself is negative.
