Coefficient is (-5)(-4) = 20.
Expo of x in the product is (x)(x^2) = x^3. That of y is (y^2)(y) = y^3.
Please, use "^" to denote exponentiation, as I have.
Answer:
The answer to your question is below
Step-by-step explanation:
1.- (x + 2)(x + 4) = x² + 4x + 2x + 8 = x² + 6x + 8
2.- (m - 5)(m + 2) = m² + 2m - 5m - 10 = m² - 3m - 10
3.- (2x + 3)(4x - 2) = 8x² - 4x + 12x - 6 = 8x² + 8x - 6
4.- (2r - 3)(r + 12) = 2r² + 24r - 3r - 36 = 2r² + 21r - 36
6.- (k - 3)(k - 1) = k² - k - 3k + 3 = k² - 4k + 3

Answer: X< -9
Step-by-step explanation: 7+2x<-11 move the constant to the right and change its sign. 2x<-11-7. Now calculate the difference, which should get to... 2x<-18. Then you just divide both sides of the inequality by 2. Which should get your answer.... X< -9
