$23,152.50
Start: $20,000
1st year: $20,000 + $1,000.00 = $21,000
2nd year: $21,000 + $1,050.00 = $22,050
3rd year: $22,050 + $1,102.50 = $23,152.50
8x + 5 = 3x + 15
8x - 3x = 15 - 5 (put same kinds of number on one side and change the signs)
5x = 10 (simplify)
5x/5 = 10/5 (simplify)
x = 2 (answer)
hope this helps
Addition information need it like the picture

where A is area
a is side a lets say its 8cm
b is side b lets say its 7 cm
theta is 28
The answer would be 89.90558242
If u round it off, the answer will be 90
