Answer:

i). x³ + 9x² + yz - 15

ii). -21m³np - 8p⁵q + mnp + 4mn + 100

Step-by-step explanation:

Question (38)

i). Two expressions are -5x² - 4yz + 15 and x³+ 4x²- 3yz

  By subtracting expression (1) from expression (2) we can the expression by addition which we can get expression (1).

 (x³+ 4x²- 3yz) - (-5x² - 4yz + 15) = x³ + 4x² - 3yz + 5x² + 4yz - 15

                                                    = x³ + 9x² + yz - 15

ii). -15m³np + 2p⁵q - 6m³pn + mnp + 4mn - 10qp⁵+ 100

  = (-15m³np - 6m³np) + (2p⁵q - 10qp⁵) + mnp + 4mn + 100

  = -21m³np - 8p⁵q + mnp + 4mn + 100

Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0
