Answer:
12x² + 17x - 5
Step-by-step explanation:
Given
(3x + 5)(4x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(4x - 1) + 5(4x - 1) ← distribute parenthesis
= 12x² - 3x + 20x - 5 ← collect like terms
= 12x² + 17x - 5
2 ok I am doing this cause I can not answer with out 20 words so that should be good now
14. Was the perimeter calculated correctly?
- Breadth = 1 *2/5 yards = 7/5 yards
We know that,
Perimeter of rectangle = 2 ( l + b )
= 2 ( 4 + 7 / 5 )
= 2 ( 20 + 7 / 5 )
= 2 × 27/5
= 54 / 5
= 1 * 4/5
No ...
47 X 4 = 188. That is 50 too many legs. 50/2=25. If you take away 25 sheep and add 25 chicken you have the correct number of legs. There are 25 chicken and 22 sheep.
