Answer:
x = 21
Explanation:
The two remaining angles must add to 90 degrees since a triangle adds to 180
3x+6 +x = 90
4x+6 =90
4x = 90-6
4x = 84
Divide by 4
4x/4 = 84/4
x = 21
Based on the vertices and the pre-order traversal order the tree would be visited is e, i, b, h, f, a, c, d, g.
<h3>What order will the tree be visited?</h3>
When using the pre-order traversal, the order would be from the root child node to the left child node to right child node.
The root node is the highest node which is e. From here you'll then proceed to the left roots first which means you'll go to i and then b.
From there you go to h and then f. The next nodes would be a and c.
Continuing from left to right, you'll then go to d and then g.
You'll therefore start from "e" and move to "i" and then "b" to "h" and then "f" and "a" to "c" and then to "" and finally to "g"

Bananas I believe I hope this help
Answer:
The inequality symbol is incorrect because she can spend up to and including $65.
The expression 5. 50b + 7. 5 is correct because $5. 50 per book is 5. 50b and that is added to the shipping fee of $7. 50 to determine the total purchase price.
Explanation:
The inequality should be 5.50b + 7.5 ≤ 65 because she can use less than $65 or all $65 to spend on books.
Also, the shipping fee is for all the books she buys combined, not for each individual book so the left side of the inequality should read 5.50b + 7.5.
I think it is the first answer choice " to explain why the Amazon Rainforest should be protected." Because that's what the passage is about. Someone explaining why the Rainforest should be protected and what will happen if it is destroyed.
