(g+1)(g+4) = 0
g = -1 and -4
You already wrote it in standard form.
It means multiply if your looking in a math problem
Answer: She has $1022 left.
Step-by-step explanation:
The total amount that Amee received an the end of year as bonus at work is $1550.
She went on a shopping spree, spending $225 at the department store, $275 at the home furnishing store, and $28 at the card shop. Therefore, the total amount that she spent at the department store, the home furnishing store, and the card shop is

Answer: The probability that exactly 2 insects will survive = 0.2501
Step-by-step explanation:
Given: A certain insecticide kills 80% of all insects in laboratory experiments.
The probability that a particular insect survives= 1-0.80=0.20
Sample size: n=14
Binomial probability distribution:
, where x= number of successes , p=probability of success in each trial, n= sample size.
The probability that exactly 2 insects will survive = 
Hence, the probability that exactly 2 insects will survive = 0.2501
