Zero of 7 with a multiplicity of 3 means one factor is 
Zero of -1 with a multiplicity of 2 means one factor is 
Zero of 5 with a multiplicity of 1 means one factor is 
Multiplying, we get

That's already in factored form so we leave it here.
There are four 5's in a deck of cards
The probability of being a 5 would be 4/52 which simplifies to 1/13
The probability of not being a 5 would be 1 - 1/13 = 12/13
The answer is
carrots - 0.8 pounds
crackers - 1.5 pounds
x - the weight of carrots
y - the weight of crackers
<span>The total weight was 2.3 pounds: x + y = 2.3
</span>
Carrots sell for $2.10 per pound: 2.10x
<span>Crackers sell for $2.90 per pound: 2.90y
</span><span>The total cost was $6.03: 2.10x + 2.90y = 6.03
</span>x + y = 2.3
2.10x + 2.90y = 6.03
_________
x = 2.3 - y
2.10x + 2.90y = 6.03
_________
2.10(2.3 - y) + 2.90y = 6.03
4.83 - 2.10y + 2.90y = 6.03
4.83 + 0.80y = 6.03
0.80y = 6.03 - 4.83
0.80y = 1.20
y = 1.20y : 0.80
y = 1.5 pounds
x = 2.3 - y = 2.3 - 1.5
x = 0.8 pounds
The reciprocal of any number is the other number you must multiply it by to equal one. In this case it's 9/2
1. C
2. 3, because I used a proportion table
