-4b(5a – 2b ) + 4(-3ab – 5b^2)

= (-20ab + 8b^2) + (-12ab - 20b^2)

= -32ab - 12b^2

= (-20ab + 8b^2) + (-12ab - 20b^2)

= -32ab - 12b^2

Subtract 4 from 12: 12 - 4 = 8;

Divide this difference by 2: 8 ÷ 2 = 4;

Multiply this quotient by 4: 4 * 4 = 16

(12 - 4)/2 * 4

= 8/2 * 4;

= 4 * 4

= 16

Divide this difference by 2: 8 ÷ 2 = 4;

Multiply this quotient by 4: 4 * 4 = 16

(12 - 4)/2 * 4

= 8/2 * 4;

= 4 * 4

= 16

Solve by using PEMDAS: 6 X 3 + 10/2. **Weegy:**
6 X 3 + 10/2
= 18 + 10/2
= 18 + 5
= 23
