Answer:
Segment BC = 36 mm or 3.6 cm
Step by Step Explanation:
There are 10 mm in 1 cm
meaning that segment AC is 40 mm long
if AB is 4 mm and it is one part of the two, then we need to subtract that from the total to find out what is left.
40 - 4 = 36
Segment BC = 36 mm or 3.6 cm
Hello,
I don't know the divison method but is it these one?
156.25= 625/4=(25/2)²
√156.25= 12.5
Answer:

Step-by-step explanation:
* Lets explain how to solve the problem
- The rule of expand the binomial is:

∵ The binomial is 
∴ a = 10k , b = -m and n = 5
∴ 
∵ 5C1 = 5
∵ 5C2 = 10
∵ 5C3 = 10
∵ 5C4 = 5
∵ 5C5 = 1
∴ 
∴ 
Answer:
The standard form of a quadratic is y = ax^2 + bx + c.
- In this equation, the formula for the axis of symmetry is x =
. - You know that the center will always be along that line, and you've got the x-coordinate already, so just plug that in and get the y-coordinate out for the center.
The vertex form of a quadratic is also helpful, y = a(x-h)^2 + k.
- In this equation, the formula for the center is (h, k), and the axis of symmetry is x = h! That's even easier!
