Simplify. Your answer should contain only positive exponents.
saveliy_v [14]

Answer:

Step-by-step explanation:

7.

2y² * 3x = 6xy²

8.

4v³ * vu²

= 4 \times 1 \times (v^{3+1})( u^2)

= 4v⁴u²

9.

4a³b² * 3a⁻⁴b⁻³

= 4 \times 3 \times a^{(3+(-4))} \times b ^{(2+(-3))}

= 12a⁻¹b⁻¹

= \dfrac{1}{12ab}

10.

x²y⁻⁴ * x³y²

= x^{2+3}y^{(-4)+2}

= x^{5}y^{-2}

= x^{5} \times \dfrac{1}{y^{2}}

11.

(x²)⁰ = 1

12.

(2x²)⁻⁴

= (2^{-4} \times x^2^{(-4)})

= \dfrac{1}{16x^8}

In a word processing document or on a separate piece of paper, use the guide to construct a two-column proof proving AC &gt; EF
VARVARA [1.3K]

<em>Answer:</em>

Complete proof is written below.

Facts and explanation about the segments shown in question :

  1. As BC = EF is a given statement in the question
  2. AB + BC = AC because the definition of betweenness gives us a clear idea that if a point B is between points A and C, then the length of AB and the length of BC is equal to the length of AC. Also according to Segment addition postulate, AB + BC = AC. For example, if AB = 5 and BC= 7 then AC = AB + BC → AC = 12
  3. AC > BC because the Parts Theorem (Segments) mentions that if B is a point on AC between A and C, then AC > BC and AC>AB. So, if we observe the question figure, we can realize that point B lies on the segment AC between points A and C.
  4. AC > EF because BC is equal to EF and if AC>BC, then it must be true that the length of AC must greater than the length segment EF.

Below is the complete proof of the observation given in the question:

<em>STATEMENT                              REASON  </em>

___________________________________________________

1. BC = EF                                    1. Given

2. AB + BC = AC                         2. Betweenness

3. AC > BC                                   3. Def. of segment inequality

4. AC > EF                                   4. Def. of congruent segments
