Answer:
1,000 + 200 + 70
Step-by-step explanation:
Expanded form is a way of writing numbers to see the math value of individual digits.
so for example:
5,000 + 300 + 20 + 3
is 5,323.

Answer:
5. x = -1
6. x = 2
Step-by-step explanation:
5. AB = 5
BC = 2x + 6
AC = x + 10
AB + BC = AC (segment addition postulate)
5 + 2x + 6 = x + 10 (substitution)
Collect like terms
5 + 6 + 2x = x + 10
11 + 2x = x + 10
2x - x = - 11 + 10
x = -1
6. AB = 9x + 7
BC = -3x + 20
AC = 39
AB + BC = AC (segment addition postulate)
(9x + 7) + (-3x + 20) = 39 (substitution)
Solve for x
9x + 7 - 3x + 20 = 39
Collect like terms
9x - 3x + 7 + 20 = 39
6x + 27 = 39
Subtract 27 from both sides
6x + 27 - 27 = 39 - 27
6x = 12
Divided both sides by 6
6x/6 = 12/6
x = 2
Answer:
Given that an image attached with this prove.
1. AD = AB, CD=CB 1. Given
2. OD = OB 2. By definition, the diagonal connecting vertec angles bisects the other diagonal
3. OA = OA 3. By reflexive property
4. triangle AOB = triangle AOD 4. By SSS congruence
5. angle AOB = angle AOD 5. By CPCTC
6. angle AOB = angle AOD = 90 6. both angles addup to 180
7. AC ⊥ DB 7. definition of right angles
