Question

Vrite an equivalent expression without parentheses. - 2(1.5h + 5) -41 -0.5+ 3h) Choose the correct answer below. A. - 3h + (-10) + 2 + (- 12h) B. - 3h + 2 + 10 + 12h o C. - 12h + ( - 10) + (- 12) + (-3h) OD. - 10h + 3+2+(-12h)

Answer 1

If we apply the distributive law, we can write our expression as

`-2(1.5h+5)-4(-0.5+3h)=-2\cdot1.5h-2\cdot5-4\cdot(-0.5)-4\cdot3h`

since -2*1.5=-3, -2*5=-10, -4*(-0.5)=2 and -4*3=-12, we have

`-2(1.5h+5)-4(-0.5+3h)=-3h-10+2-12h`

the, by comparing this result with the options, the answer is option A
