Answer:
105ft per minute
Step-by-step explanation:
well, if he/she walks 7ft in 4s, then you divide 60/4. In which you get 15.
15•7=105
Answer:
7/4
Step-by-step explanation:
use cross multiplication and you are going to end up dividing 12 by 3 to get four as your denominator
Answer:
Step-by-step explanation:
The ratio 15:17 cannot be reduced, so 15/17 itself is in lowest terms.
Answer:
2x² − 4x + 3
Step-by-step explanation:
x = 2/3 is a root of both the numerator and the denominator, so it divides evenly. Therefore, one method is to factor by grouping:
6x³ − 16x² + 17x − 6
6x³ − 4x² − 12x² + 17x − 6
2x² (3x − 2) − (12x² − 17x + 6)
2x² (3x − 2) − (4x − 3) (3x − 2)
Divided by 3x − 2:
2x² − (4x − 3)
2x² − 4x + 3
Another method is to use long division (see image).
Answer:
20
Step-by-step explanation:
This is a right triangle
a² + b² = c²
16² + 12² = x²
256 + 144 = x²
400 = x²
take the square root of both sides
x = 20
