6 kids like tennis
12 kids like football
Answer:
10x³ + 28x² - 12x - 18
Step-by-step explanation:
Given
(5x² - x - 3)(2x + 6)
Each term in the second factor is multiplied by each term in the first factor, that is
5x²(2x + 6) - x(2x + 6) - 3(2x + 6) ← distribute the parenthesis
= 10x³ + 30x² - 2x² - 6x - 6x - 18 ← collect like terms
= 10x³ + 28x² - 12x - 18
1. There are no like terms, it is in its simplest form.
2. 3(3m+2)(m-8)
3. 3(3m+10)(2m+7)
4. 3(3x-7)(2x-9)
5. 4(2x+11)(2x-11)
6. 5(4x-3)(x+8)
Answer: 27
Step-by-step explanation:
Since we are informed that Gianna practices penalty kicks and that she made 18/24 of her penalty kicks yesterday, this will be converted to its simplest form which will be:
= 18/24 = 3/4 .
If she plans on shooting 36 penalty kicks, the number of penalty kicks that Gianna would have to make to successfully shoot an equivalent fraction as yesterday will be:
= 3/4 × 36
= 3 × 9
= 27 penalty kicks.
