I gave u the answer I’m a math kid
For the given expression X² -3X + n and it is a perfect square trinomial.
The perfect square trinomial is in forms below:
(a-b)²
(a+b)²
When we assign n=9/4, we will have the equation below:
X² - 3X +9/4
=(X-(3/2))²
Therefore, the answer is "9/4".
Answer:
Step-by-step explanation:
f(x) = 2/3 x + 3
This has the meaning that whatever you see in the backets on the left, you put in the x on the right.
f(12) = 2/3 (12) +3
2/3 12 = 4 * 2 = 8
f(12) = 8 + 3
f(12) = 11
The simplified form of the expression is -10x - 16
<h3>Factorizing expressions</h3>
Given the expression -2(5x + 8)
In order to factorize the expression, we will use the distributive property. Distribute -2 over 5x and 8 to have:
Step 1: Distribute -2 to 5x and 8
-2(5x + 8) =-2(5x) -2(8)
Simplify
-2(5x + 8) = -10x - 16
Hence the simplified form of the expression is -10x - 16

Answer:
39
Step-by-step explanation:
We notice this is an arithmetic sequence.
14, 9, 4.
common difference = d = 14 - 9 = 5
first term a_1 = 14
Find 6th term a_6
a_n = (n -1)*d + a_1
a_6 = (6 -1)*5 + 14
a_6 = 5*5 + 14 = 25 + 14 = 39
