Answer:
1. $12
2. 3 boxes
3. 2 boxes
Step-by-step explanation:
1. You first need to find the dollar amount each of them sold. To do this, you need to find the lowest common multiple for 4 and 6. The lowest common multiple is 12.
2. Kevin sells boxes of cookies for $4 each so, you need to find the value of X in this equation: 4 . X = 12. The value of X is 3.
3. Laura sells boxes of cookies for $6 each so we need to find the value of X in this equation: 6 . X = 12. X = 2 because that is the only answer that makes since.
<em>A. x ≤ - 9 or x ≥ 9</em>
- Step-by-step explanation:
<em>x² ≥ 81</em>
<em>| x | ≥ 9</em>
<em>x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)</em>
<em>x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]</em>
<em>x ∈ ( -oo ; - 9 ] ∪ [ 9 ; + oo)</em>
