B: 3 and 4 because they both do not have an = sign
No 5/8=62.5% and that means 5/8 is greater that 60%
You simply need to subtract 3 dollars from twenty one, which would be 18.
Now you divide 18 by 4.75. Which is 3.78.
With this result, you just need to round it off, money wise. So she paid for 3 games.
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:
1 and 2 are adjacent
Step-by-step explanation:
1 and 2 are congruent because 90 is been bisected in two equal parts 1 and 2
1 and 2 form right angle and complementary angle because 1 + 2 = 90
