Answer + Step-by-step explanation:
1) D be the symmetric of B with respect to C then CD = BC
A the symmetric of C with respect to B then AB = BC
We obtain :
CD = BC
AB = BC
Then AB = CD
2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD
3) we have :
BA = CD
BS = CS
m∠SBA = m∠SCD
Then
the triangles SBA and SCD are congruent
4)
the triangles SBA and SCD are congruent Then SA = SD
Therefore SAD is an isosceles triangle.
Not similar, since the ratio of corespondent side is not constant
suppose ∆PRQ ~ ∆MRN, then RN/RP = RM/RQ but the reality contradict
Answer:
answer of 2a)
He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then
24–16=a
His new account balance is $8.
He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then
8+b=28
His deposited $20 in his account.
He has $28 and spent $34. Let c represent his account balance after he bought the book. Then
28–34=c
His new account balance is -$6.
He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then
−6+d=0
He deposited $6.
answer of 2b)
If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Answer: Total cost =$24338.95
Step-by-step explanation:
The new car costs $19,820.00.
He has to pay 17.25% in taxes based off the cost of the car. This means 17.25% of $19,820.00
=(17.25/100)×19,820.00
=0.1725 ×19820.00 = $3418.95
Cost of taxes = $3418.95
If he also purchases an extended warranty for $1,100.00
Cost of taxes plus extended warranty
= $3418.95 + $1,100.00 = $4518.95
what is a reasonable estimate for the total price of the car? This means the actual cost of the new car + Cost of taxes + cost of extended warranty.
Total cost = $19,820.00 +$3418.95 + $1,100.00= $24338.95
