Answer:
None.
Step-by-step explanation:
The coefficients are a=1, b=-3, c=8, so the discriminant is ...
... b²-4ac = (-3)²-4(1)(8) = 9-32 = -23
This negative value means both the roots are complex.
Answer:
the answer is -97, -83, -21, 34, 55, 56
Step-by-step explanation:
The simple way to put it is negitives are backwards, the bigger the number the lesser it gets. So always put the highest negitive as least, hope this helps!
Answer: n = 10
Step-by-step explanation:
Dividing exponents results to subtracting them. 8-(-6) is 14. Multiplying negative numbers together results in positive numbers. the exponent 14 - 4 is 10. So n = 10.
Answer:
225 inches²
Step-by-step explanation:
Let the length be l and width be w
Condition 1
2l+2w=68 (Perimeter=68)--------(i)
Condition 2
l=3w-2 ---------(ii)
Putting equation (ii) in (i)
2(3w-2)+2w=68
6w-4+2w=68
8w-4=68
8w=68+4
8w=72
dividing both sides by 8
w=9 inches
now putting w=9 in (ii)
l=3(9)-2
l=27-2
l=25 inches
Now
Area of rectangle = l × w
=9 × 25
=225 inches²
