Answer:
Step-by-step explanation:
x(6.75) + (5 - x)(5.50) = 5(6.25)
6.75x + 27.5 - 5.50x = 31.25
1.25x = 3.75
x = 3 lb of seed A
Perform indicated operations on left side
x*x+4x+4x+4*4=9
x^2+4x+4x+16=9 combine like terms on left side
x^2+8x+16=9 subtract 9 from both sides
x^2+8x+7=0 factor
x^2+x+7x+7=0
x(x+1)+7(x+1)=0
(x+7)(x+1)=0
x=-1, -7
