What value ofx is in the solution set of 3(x-4)>5x +2?
kvv77 [185]

\boldsymbol{\sf{3(x-4) > 5x +2 }}

Use the distributive property to multiply 3 by x−4.

\boldsymbol{\sf{3x-12 > 5x+2 }}

Subtract 5x on both sides.

\boldsymbol{\sf{3x-12-5x > 2 } }

Combine 3x and −5x to get −2x.

\boldsymbol{\sf{-2x-12 > 2 }}

Add 12 to both sides.

\boldsymbol{\sf{-2x > 2+12 \ \longmapsto \ \ [Add \ 2 +12]}}

\boldsymbol{\sf{-2x > 14}}

Divide both sides by −2. Since −2 is < 0, the inequality direction is changed.

\boldsymbol{\sf{x < \dfrac{14}{-2} \ \ \longmapsto \ \ \ [Split]}}

\boxed{\boldsymbol{\sf{x < -7 }}}

So in the <u>inequality 3(x-4)>5x +2</u>, the value of x is -7.

if each side of a square classroom is 25 feet then what is the perimeter of the room? what is the area of the floor of the room?
Svetllana [295]

Answer:

P = 100

Area = 625

Step-by-step explanation:

Area = s^2

sqrt(area) =  sqrt(s^2)

area = 25*25

sqrt(25*25) = sqrt(s^2)

s = 25

P = 4*s

P = 4 * 25

P = 100

Area = s^2

s = 25

Area = 25^2

Area = 625
