-4b(5a – 2b ) + 4(-3ab – 5b^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

4x = 10 - 18
4x = -8
x = -8/4
x = -2

12x – 17 = -41
12x = -41 + 17
12x = -24
x = -24/12
x = -2

Let's solve your equation step-by-step.
12x 17= 41
Step 1: Add +17 to both sides.
12x 17+17= 41+17
12x= 24
Step 2: Divide both sides by 12.
12x12= 24
12x= 2
Answer:
x= 2

Simplify the following expression using PEMDAS 6 + 3 x 42 – 7 PLEASE SHOW THE DIFFERENTS STEPT
Weegy: 6 + 3 x 42 – 7 a. 3 x 42 first = 126, so it would now be 6 + 1266 -7 b. 6 + 126 = 132, so it would now be 132 - 7 c. finally, 132 - 7 = 125 User: Simplify the following expression using PEMDAS 3 + 4[(8 ÷ 2) + 3]PLEASE SHOW THE DIFFERENTS STEPT Weegy: 3 + 4[(8 ÷ 2) + 3] a. (8 ÷ 2) = 4 b. [4 + 3] = 7 c. 3 + 4 + 7 = 14 User: Simplify the following expression using PEMDAS (6÷ 3) + 4(6÷2)2 PLEASE SHOW THE DIFFERENTS STEPT Weegy: (6÷ 3) + 4(6÷2)2 a. (6÷ 3) = 2 amd (6÷2) = 3, so now it would be 2 + 4 x 3 x 2 b. 4 x 3 = 12 c. 12 x 2 = 24 d. 2 + 24 = 26 (More)
