Question

select all expressions that are equivalent to -3(0.15-0.2+0.25p) A. -0.45-0.6+0.25pB. 0.15-0.75pC. 3(0.15+0.2+0.25p)D. -3(-0.05+0.26p)E. -3(0.05+0.25)

Answer 1

1) Let's start by operating that expression:

-3(0.15-0.2+0.25p) Distribute the factor

-0.45 +0.6-0.75p Combine like terms

0.15 -0.75p

In addition to this, we can rewrite within the parentheses the following expression -3(0.15-0.2+0.25p) as -3(-0.05+0.25p) and if we multiply

-3(0.15-0.2+0.25p) by -1 we'd have 3(-0.15+0.2-0.25p)

3(0.05-0.25p)

2) So the answer is:

B,
