The GCF of 15 and 25 would be 5
Multiply complex numbers 5+6i and 5-6i in the same way as you multiply binomials.
By definition, i² is -1.
Do the multiplications.
Now cancel -30i & +30i
Now the equation becomes

Answer:
- 35 5-lb weights
- 25 3-lb weights
Step-by-step explanation:
Let t and f represent the numbers of three- and five-pound weights. The problem statement tells us ...
f + t = 60
f - t = 10
Adding these two equations, we get ...
(f +t) +(f -t) = (60) +(10)
2f = 70 . . . . . eliminate parentheses
f = 35 . . . . . . divide by 2
She has 35 5-lb weights, and 25 3-lb weights.
Simple, first we add the numbers up. 3+3+3+3=12, you asked what is the probability that it is a bag of peanuts, their are 3 bags of peanuts. Let's make a fraction. The fraction is going to be 3/12, we can simplify 3/12 into 1/4. So, the answer is A. 1/4
