When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
LETTER B
Point B and Point C.

Answer: Longest distance she could measure is 70 mm
Step-by-step explanation:
To find the longest distance from one side to other across the center we have to find the diameter of the lampshade.
As it is given that the distance around the lampshade is 219.8 mm which is equal to the circumference of the lampshade.
Circumference of the lampshade is
πD, where D is the diameter of the lampshade
where the value of π=3.14
Divide both sides by 3.14 we get

on solving we get

Answer:
1. Commutative Property
2. Associative Property.
3. Identity Property.
4. Distributive Property.
Answer:
Step-by-step explanation:
Assuming that you meant 6(7x - x), we get: 6(6x) = 36x
