X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.
Answer: 9
Step-by-step explanation:
We will use the Order of Operations to solve.
Given:
4 – 15 ÷ (30 – 33)
Subtract 33 from 30:
4 – 15 ÷ (– 3)
Divide -15 by -3:
4 + 5
Add 4 to 5:
9
Answer:
I think its $6894.21
Step-by-step explanation:
compound interest formula: A= P(1+ r/n)^nt
