The
distributive property in a given field combines multiplication with addition,
that is in a field <span>F<span>,
any elements <span><span><span>a<span>,b</span></span> and </span><span>c which
satisfy the following rule:</span></span></span></span>
<span>a(b+c<span>)=</span><span>ab</span>+<span>ac</span></span>
<span><span>
</span>
</span>
<span>The whole
numbers are a subset of the field </span><span>R,
which is composed of all rational and irrational numbers, hence the whole
numbers satisfy this property. Therefore, if I wish to multiply 5 and 10, I can
split this down to simplify the problem (or simply highlight the logical
reasoning behind how long multiplication works.) To demonstrate:</span>
<span>5∗10=5∗(2+8<span>)=</span>5∗2+5∗8=10+40=50</span>

If you would like to know how much do two apples cost, you can calculate this using the following steps:
o ... the cost of one orange
a ... the cost of one apple
1 * o + 1 * a = $1.05
2 * o + 3 * a = $2.75
_______________
o + a = 1.05 ... o = 1.05 - a
2 * o + 3 * a = 2.75
2 * (1.05 - a) + 3 * a = 2.75
2.1 - 2 * a + 3 * a = 2.75
a = 2.75 - 2.1
a = $0.65
o = 1.05 - a = 1.05 - 0.65 = $0.4
2 * a = 2 * 0.65 = $1.3
The correct result would be: Two apples cost $1.3.
You are subtracting -16-4
So I would assume your answer would be C
I hope this answer helps!
Answer: 20 i think srry if its wrong
Step-by-step explanation:
Answer : -4a+10
Substitute (a-3) for x
-4(a-3)-2
-4a+12-2
-4a+10 but can also be written as -2(2a-5)
