$3x(4x^4-5x)=(3x)(4x^4)-(3x)(5x)=(3\cdot4)x^{1+4}-(3\cdot5)x^{1+1}\\\\=\boxed{12x^5-15x^2}$

Find all points having an x coordinate of 5 whose distance from the point (2,2) is 5.

stepan [7]

Answer:

(5,6) , (5,-2)

Step-by-step explanation:

Let the required point be P(5,y).

Its distance from (2,2) is 5 units.

So, $(5-2)^{2}$ + $(y-2)^{2}$ = 25.

So, $3^{2}$ + $(y-2)^{2}$ = 25.

9 + $(y-2)^{2}$ = 25.

$(y-2)^{2}$ = 16

Two cases are possible for now

case 1 : y-2 = 4 .

y = 6

required point will be (5,6)

case 2 : y - 2 = -4.

y = -2.

required point will be (5,-2).

Two points are possible : (5,6) , (5,-2).
