The answer is C
Step-by-step explanation:
The gardener planted 665 strawberries

Answer:
- |w -30| > 1.6
- (-∞, 28.4) U (31.6, ∞)
Step-by-step explanation:
1. The snack bags will be rejected if their weight differs from 30 grams by more than 1.6 grams:
|w -30| > 1.6
__
2. This inequality resolves to two inequalities.
w -30 > 1.6
w > 31.6 . . . . . add 30
and
-(w -30) > 1.6
w -30 < -1.6 . . . multiply by -1
w < 28.4 . . . . . add 30
The solution in interval notation is the union of the two disjoint intervals:
(-∞, 28.4) U (31.6, ∞)
B I assume, not 100% sure
Step-by-step explanation:
The root is
-sqr root of 5.
First, we put these roots in the forn of
where a is the root
So we have
To get rid of that square root, let have another root that js the conjugate posive root of 5.
Which will gives us a rational coeffeicent of degree 4.
Why we didn't do
?
Because
If we foiled out we will still have a irrational coeffceint.
