Answer:
1. (x-3)(x+2)
2. (x-5)(x-3)
3. x= 2,1
4. x= -2,-4
5. x= 3,-7
6. x= 1,-8
7. x= 5,-7
8. x= -1/3,-2
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
4n - 12 < 2n + 2 is for n=6
4×6 -12 < 2×6 +2
24 - 12 < 12 + 2
12 < 14 correct
for n=7
4×7 - 12 < 2×7 + 2
16 < 16 incorrect
for n=8
4×8 - 12 < 2×8 + 2
20 < 18 incorrect
for n=9
4×9 - 12 < 2×9 + 2
24 < 20 incorrect
so, only for n=6 is the expression true.
Answer:
Her speed is = 36.58 mi/h
Step-by-step explanation:
To convert 59 km/h into mi/h, we use that 1 km = 0.62 miles. Then, we can directly replace the unit "km" in the expression for the velocity, with 0.62 miles and operate the explicit product of 59 times 0.62:
59 km/h = 59 (0.62 mi)/h = 36.58 mi/h
D) I hope this answer helped :)
