<em>Answer:</em>
<em>2 whole 1/4</em>
<em>Step-by-step explanation:</em>
<em>When forming a perfect square trinomial you need to "complete the square".
</em>
<em>All of the steps to completing the square when solving an equation:
</em>
<em>1. The leading coefficient must be 1. </em>
<em>2. Divide b by 2.
</em>
<em>3. Square (b/2)
</em>
<em>4. Add (b/2)^2 to both sides to keep the polynomial balanced.
</em>
<em>5. You can now write the perfect square trinomial and solve.
</em>

x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
Answer:
a.–12 – 18
Step-by-step explanation:
We have to compute the difference (the subtraction) between the new, colder temperature, which is equal to -12 °C, and the original temperature, which is equal to 18 °C, that is:
colder temperature - original temperature
Replacing with data:
-12 °C - 18 °C = -30 °C
Well, it would be 302.1 as three is lowere than five, and when its lower you just leave it. if its five or higher than you round up. hope that helps! :)
