Answer:
Let's find unit price. 7.38 / 2 = 3.69 and 9.57 / 3 = 3.19. Since 3.19 < 3.69 the better buy is 9.57 for 3 pounds.
65x^2 + 212x - 133
you have to use the quadratic formula
x=( -b +/- √b²-4ac) / 2a
a is 65
b is 212
c is 133
because the first value is squared you will have 2 answers
x= 7/13
x= - 19/5
Subtract b and then a = (zma) - b
Answer:
622.27
Step-by-step explanation:
- $87.45 + (- $24.76) + (-17.29) = $-129.5
$143.87 + $348.90 = $492.77
492.77 - (-129.5) = 622.27
