Simplify the given polynomial and use it to complete the statement (8x^2 - 5x -7) - (9x^2 - 3x -5) + (x+7)(x + 1)
Lunna [17]

Answer:

The answer to your question is:    6x + 5

Step-by-step explanation:

                          (8x² - 5x -7) - (9x² - 3x -5) + (x+7)(x + 1)

                          8x² - 5x - 7 - 9x² + 3x + 5 + x² + 8x + 7

                          9x² - 9x² - 5x + 11x + 12 - 7

                         6x + 5

HELP ME <br> solve for the right triangle
VikaD [51]

Answer:

see explanation

Step-by-step explanation:

Using the cosine and tangent ratios in the right triangle

cos41° = \frac{adjacent}{hypotenuse} = \frac{VW}{VX} = \frac{7}{VX}

Multiply both sides by VX

VX × cos41° = 7 ( divide both sides by cos41° )

VX = \frac{7}{cos41} ≈ 9.3

-----------------------------------------------------------------------

tan41° = \frac{opposite}{adjacent} = \frac{WX}{VW} = \frac{WX}{7}

Multiply both sides by 7

7 × tan41° = WX, thus

WX ≈ 6.1

-------------------------------------------------------------------------

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for ∠ X

∠ X = 180° - (90 + 41)° = 180° - 131° = 49°
