An airplane flying with the wind can cover a certain distance in 2 hours. The return trip against the wind takes 2.5 hours. Find
Anna [14]

Answer:

Wind speed = 30 mph

Plane speed = 270 mph

Step-by-step explanation:

Given that :

Distance = 600 miles

Let speed of airplane = a ; speed of wind = b

Net speed ; with wind = a + b

Net speed against wind = a - b

Time taken with wind = 2 hours

Time taken against wind = 2.5 hours

Recall :

Speed = distance / time ; distance = speed * time

(a + b) * 2 = (a - b) * 2.5

2a + 2b = 600

a + b = 300 - - - (1)

a = 300 - b

2.5a - 2.5b = 600

a - b = 240 - - - (2)

300 - b - b = 240

300 - 2b = 240

-2b = - 60

b = 30

a = 300 - 30

a = 270

Wind speed = 30 mph

Plane speed = 270 mph

Which expression is eqivalent to (x^2-3x)(4x^2+2x-9)
IceJOKER [234]

For this case we must find an expression equivalent to:

(x ^ 2-3x) (4x ^ 2 + 2x-9) =

Applying distributive property considering that:

- * + = -\\- * - = +\\x ^ 2 * 4x ^ 2 + x ^ 2 * 2x-x ^ 2 * 9-3x * 4x ^ 2-3x * 2x + 3x * 9 =

To multiply powers of the same base, the same base is placed and the exponents are added:

4x ^ 4 + 2x ^ 3-9x ^ 2-12x ^ 3-6x ^ 2 + 27x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

4x ^ 4-10x ^ 3-15x ^ 2 + 27x

Answer:

An equivalent expression is: 4x ^ 4-10x ^ 3-15x ^ 2 + 27x
