Answer:

-3x⁴ + 8x³ - 9x² - 7x - 9

General Formulas and Concepts:

  • Combining like terms

Step-by-step explanation:

<u>Step 1: Define expression</u>

(5x³ - 3x⁴ - 2x - 9x² - 2) + (3x³ + 2x² - 5x - 7)

<u>Step 2: Simplify</u>

  1. Combine like terms (x³):                    -3x⁴ + 8x³ - 9x² - 2x - 5x - 2 - 7
  2. Combine like terms (x):                     -3x⁴ + 8x³ - 9x² - 7x - 2 - 7
  3. Combine like terms (constants):       -3x⁴ + 8x³ - 9x² - 7x - 9

A plane traveled 2565 miles with the wind in 4.5 hours and 2205 miles against the wind in the same amount of time. Find the spee
kherson [118]

Answer:

  • plane: 530 mi/h
  • wind: 40 mi/h

Step-by-step explanation:

Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...

  speed = distance/time

  p +w = (2565 mi)/(4.5 h) = 570 mi/h

  p -w = (2205 mi)/(4.5 h) = 490 mi/h

Adding these speeds, we get ...

  (p +w) +(p -w) = (570) +(490) mi/h

  2p = 1060 mi/h

  p = 530 mi/h

Then the speed of the wind is ...

  w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h

The plane's speed is 530 mi/h; the wind speed is 40 mi/h.

Hey can you please help? I am struggling a lot don’t know how to solve this
Ket [755]

Answer:

64.8

Step-by-step explanation:

Pythagoreon Theroem

a^2 + b^2 = c^2  in  this situation it would actually be the opposite, seeing where the "x" is (on a leg) c^2 - b^2 = a^2. First  take the square of 67 and 17

67 squared is 4489 and 17 squared is 289 then  subtract both results

4489-289 = 4200 take the square root of this number

64.8074  (Round to the tenths 64.8)
