Please help on these questions that I got wrong.

Since x equals -3 the expression looks like this after expanding it: 2*(-3)+6= 0. So the answer to A is 0. After expanding equation B it will look like this: 10x+20. 10x equals -2. The expression now looks like this: 10*(-2)+20=0.

After expanding equation C the expression looks like this: 8x+4. x=(-0.5). The equation(C) now looks like: 8*(-0.5)+4 which equals 0.

After expanding equation D) the equation looks like this: 6x-24y. x equals 4 and y equals 0.25. The equation (D) now is this: 6*4-24*0.25 which equals 18. So,

Answer to A) 0

Answer to B) 0

Answer to C) 0

Answer to D) 18
