kati45 [8]

Answer:

D

Step-by-step explanation:

So we have the expression:

(3x^2-5x+6)+(9-8x-4x^2)

Combine like terms:

=(3x^2-4x^2)+(-5x-8x)+(6+9)

Add or subtract:

=(-1x^2)+(-13x)+(15)

Simplify:

=-x^2-13x+15

Our answer is D

Which expression is equivalent to 6m+(m-2)(m+7)+3
Vika [28.1K]

Answer:

m^{2} + 11m - 11

Step-by-step explanation:

6m+(m-2)(m+7)+3  =   6m   +  [ m*m - 14 -2m + 7m]  + 3

=  6m  + mm - 14 + 5m  + 3

=  mm + 11m - 11

6m+(m-2)(m+7)+3   = m^{2} + 11m - 11

A moterboat that ravels with a speen of 20km/hour in still water has traveld 20 km against the current and 180km with the curren
Ira Lisetskai [31]

Answer:

10 kph

Step-by-step explanation:

Find the speed of the current of the river.

20/(20 - c) + 180/(20 + c) = 8

20(20 + c) + 180(20 - c) = 8(400 - c^2)

8c^2 - 160c  + 800 = 0

8(c^2 - 20c + 100) = 0

8(c - 10)^2 = 0

c = 10

The speed of the current of the river is 10 km/hour.
