Hello!
First you can make an equation
103 + 35 + x + x + x / 5 = 39
Combine like terms
138 + 3x / 5 = 39
Multiply both sides by 5
138 + 3x = 195
Subtract 138 from both sides
3x = 57
Divide both sides by 3
x = 19
Now you add all the numbers up to get the sum
103 + 35 + 19 + 19 + 19 = 195
So the answer is (i) is 195
The answer is (ii) is 19
Hope this helps!
Firstly, subtract 3 on both sides of the equation:
Next, divide by a:
Lastly, square root both sides, and your answer will be
(x+1)(2x+1)(x-2)
= (2x+1)(x+1)(x-2)
= (2x+1)(x² -x - 2)
= 2x³ - 2x² - 4x + x^2 - x - 2
= 2x³ - x² - 5x - 2
Answer: 2x³ - x² - 5x - 2
