Answers:
21.) (A) √7 < 2.8
22.) (C) 2 1/3 = 2.33..
23.) (A) √30 < 5.6
24.) (C) 3, √12, 3 1/2, 3.55..
It's C, Reflexive Property. Reflexive Property is basically that the value equals itself, hence the a = a.
Answer:
wth is this typa math
Step-by-step explanation:
i dunno
Answer:
Answer is option a and b and d
Step-by-step explanation:
- Tomas needs exactly 12 potatoes to make 24 potato pancakes
- Tomas needs exactly 18 potatoes to make 36 pancakes
- Tomas need exactly 30 potatoes to make 60 pancakes
- Option a and b and d are correct
Because 12 is twice aa 6
24 is twice as 12
36 is twice as 18
60 is twice as 30

Answer:
z = x^3 +1
Step-by-step explanation:
Noting the squared term, it makes sense to substitute for that term:
z = x^3 +1
gives ...
16z^2 -22z -3 = 0 . . . . the quadratic you want
_____
<em>Solutions derived from that substitution</em>
Factoring gives ...
16z^2 -24z +2z -3 = 0
8z(2z -3) +1(2z -3) = 0
(8z +1)(2z -3) = 0
z = -1/8 or 3/2
Then we can find x:
x^3 +1 = -1/8
x^3 = -9/8 . . . . . subtract 1
x = (-1/2)∛9 . . . . . one of the real solutions
__
x^3 +1 = 3/2
x^3 = 1/2 = 4/8 . . . . . . subtract 1
x = (1/2)∛4 . . . . . . the other real solution
The complex solutions will be the two complex cube roots of -9/8 and the two complex cube roots of 1/2.
