First, you’d look at what can multiply together to make 20. You can multiply 10x2, 1x20, or 4x5 (or change them so each number is a negative) to make a positive 20. You then must look at which one of these can be added or subtracted together to create -9. Negative 4 and 5 can be subtracted to make -9, so you would factor them out, as well as the x^2, and get the answer (x-4)(x-5).

Answer: (x-4)(x-5)

Difference between compounded annually, monthly and daily.
zvonat [6]

Answer:

With monthly compounding, the bank will calculate interest on your account just once per month. It will not update your balance on a daily basis when it calculates how much interest it owes you. Assuming that the APR is the same, accounts with monthly compounding offer a lower APY than accounts with daily compounding.

1. Your furniture store sells two types of dining room tables. The first, type A, costs $265 and you make a $25 profit on each o
Gnom [1K]
Let x represent the number of type A table and y represent the number of type B tables.
Minimize: C = 265x + 100y
Subject to: x + y ≤ 40
25x + 13y ≥ 760
x ≥ 1, y ≥ 1

From, the graph the corner points are (20, 20), (39, 1), (30, 1)
For (20, 20): C = 265(20) + 100(20) = $7,300
For (39, 1): C = 265(39) + 100 = $10,435
For (30, 1): C = 265(30) + 100 = $8,050

Therefore, for minimum cost, 20 of type A and 20 of type B should be ordered.
