Answer 2

To evaluate the expression (8y³-5y):y+(y-4)²-(3y+1)² when y = 1.5, we substitute the value of y into the expression and perform the calculations. Let's break it down step by step:

Step 1: Substitute the value of y into the expression. (8(1.5)³-5(1.5))/(1.5)+((1.5)-4)²-(3(1.5)+1)²

Step 2: Simplify the expression inside the parentheses. (8(3.375)-7.5)/(1.5)+(-2.5)²-(4.5+1)²

Step 3: Perform the multiplications and additions. (27-7.5)/(1.5)+6.25-(5.5)²

Step 4: Simplify further. 19.5/1.5+6.25-30.25

Step 5: Perform the division and subtraction. 13+6.25-30.25

Step 6: Perform the addition and subtraction. -10.75

Therefore, when y = 1.5, the value of the expression (8y³-5y):y+(y-4)²-(3y+1)² is -10.75.
