The number that has to fill the blank to make the trinomial a <em>perfect square</em> is 72x
<h3>Perfect square trinomial </h3>
From the question, we are to determine the number that makes the given trinomial a perfect square
The given trinomial is
9x² + ___+ 144
For any given trinomial ax² + bx + c, the trinomial is a perfect square if
b² = 4ac
In given trinomial,
a = 9, c = 144, b = ?
Now, we will determine the value of b
Putting the values into the equation,
b² = 4ac
b² = 4×9×144
b² = 5184
b = √5184
b = 72
Thus,
The trinomial will become 9x² + 72x+ 144
Hence, the number that has to fill the blank to make the trinomial a <em>perfect square</em> is 72x

Answer:
C. (5,3)
Explanation:
I worked it out. If you plug in 5 for all the x’s and 3 for the y’s, it will work out right.
Answer:
Red is 3/10
yellow is 1/3
Step-by-step explanation:
since there is 10 marbles all together it will be out of 10
and since there is 3 red marbles the probability is 3/10
but when you take out one of the marbles the total amount of marbles in the bag is 9. since there is 3 yellow marbles in the bag it would be 3/9 which can be simplified to 1/3
