The answer is D (- 4x^2 - 3x - 5)
Explanation:
- 4f(x) - 3g(x)
= - 4(x^2 + 5) - 3(x - 5)
= - 4x^2 - 20 - 3x + 15
= - 4x^2 - 3x - 5
Integers are whole numbers.
mixed number are whole numbers plus fractions...that when simplified, become improper fractions
2 1/2 = 5/2....this is not an integer or a whole number
3 1/4 = 13/4....same here...not an integer or a whole number
4 1/3 = 13/3...not an integer or a whole number
Answer:
4

Answer:
16 - Original number of chocolates in the box.
Step-by-step explanation:
C = 6 / (3/8) =6 x (8/3) =48 / 3 = 16
Step-by-step explanation:
Using the identity a² - b² = (a + b) (a - b)
=> (3 {p - q})² - (5 {q - r})²
=> [(3 {p - q}) + (5 {q - r})] [(3 {p - q}) - (5 {q - r})]
=> [(3p - 3q) + (5q - 5r)] [(3p - 3q) - (5q - 5r)]
=> [3p - 3q + 5q - 5r] [3p - 3q - 5q + 5r]
=> [3p + 2q - 5r] [3p - 8q + 5r]
