Dan thought of two numbers. Their product is 2020. If he increases each of his numbers by 1, the product of the new numbers is 2000.
If he decreases each of his original numbers by 2, what is the product of the resulting numbers?

What is the standard form of -5x^2+2x^4-11+x^3+3x

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)
