It's the last answer. Think about when you move a point on a graph left 4 spaces it's on the x axis. Because it's going left it's going towards the negative numbers hence minus and not plus. some concept for the y axis.
2 is a factor of 4x + 2y
2( 2x + y)
Based on the calculations, the value of the given prefix expression is equal to 2205.
<h3>What is
preorder traversal?</h3>
The preorder traversal of a tree (T) are typically used in discrete mathematics to determine the value of a prefix expression on a specific expression tree.
For the preorder traversal of this tree (T), we would start from the right most expression:
Prefix expression = * + 3 + 3 ↑ 3 + 3 3 3
Prefix expression = * + 3 + 3 ↑ 3 6 3
Prefix expression = * + 3 + 3 3⁶ 3
Prefix expression = * + 3 3 729 3
Prefix expression = * + 3 732 3
Prefix expression = * 735 3 ⇒ 735 × 3
Value = 2205.

<u>Complete Question:</u>
Given the following prefix expression:
* + 3 + 3 ↑ 3 + 3 3 3
What is the value of the prefix expression?
20t^2+9t-20 is the answer
Answer:
a = 0.5454545455
Step-by-step explanation:
Simplifying
3(a + 2) + 4(2a + -3) = 0
Reorder the terms:
3(2 + a) + 4(2a + -3) = 0
(2 * 3 + a * 3) + 4(2a + -3) = 0
(6 + 3a) + 4(2a + -3) = 0
Reorder the terms:
6 + 3a + 4(-3 + 2a) = 0
6 + 3a + (-3 * 4 + 2a * 4) = 0
6 + 3a + (-12 + 8a) = 0
Reorder the terms:
6 + -12 + 3a + 8a = 0
Combine like terms: 6 + -12 = -6
-6 + 3a + 8a = 0
Combine like terms: 3a + 8a = 11a
-6 + 11a = 0
Solving
-6 + 11a = 0
