Full solution

Q. Find the value of 4y(y+3)(2+10)4y - (y + 3)(2 + 10) when y=5y = 5.
  1. Substitute y value: Step 11: Substitute the value of y into the expression.\newlineCalculation: Substitute y=5y = 5 into 4y(y+3)(2+10)4y - (y + 3)(2 + 10).\newline4(5)(5+3)(2+10)4(5) - (5 + 3)(2 + 10)
  2. Simplify inside parentheses: Step 22: Simplify inside the parentheses.\newlineCalculation: Simplify 5+35 + 3 and 2+102 + 10.\newline4(5)(8)(12)4(5) - (8)(12)
  3. Perform multiplication: Step 33: Perform the multiplication.\newlineCalculation: Multiply 44 by 55 and 88 by 1212.\newline209620 - 96
  4. Subtract results: Step 44: Subtract the results.\newlineCalculation: Subtract 9696 from 2020.\newline2096=7620 - 96 = -76
