(5x+2) and {3(x+14)} what is

Mathematics
1 answer:
Phoenix [80]4 years ago
7 0

Answer:

Step-by-step explanation:

x=20

Reorder the terms:

(2 + 5x) = 3(x + 14)

Remove parenthesis around (2 + 5x)

2 + 5x = 3(x + 14)

Reorder the terms:

2 + 5x = 3(14 + x)

2 + 5x = (14 * 3 + x * 3)

2 + 5x = (42 + 3x)

Solving

2 + 5x = 42 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

2 + 5x + -3x = 42 + 3x + -3x

Combine like terms: 5x + -3x = 2x

2 + 2x = 42 + 3x + -3x

Combine like terms: 3x + -3x = 0

2 + 2x = 42 + 0

2 + 2x = 42

Add '-2' to each side of the equation.

2 + -2 + 2x = 42 + -2

Combine like terms: 2 + -2 = 0

0 + 2x = 42 + -2

2x = 42 + -2

Combine like terms: 42 + -2 = 40

2x = 40

Divide each side by '2'.

x = 20

Simplifying

x = 20

Consider a room that is 20 ft long, 15 ft wide, and 8 ft high. For standard sea level conditions, calculate the mass of air in t
irga5000 [103]

Answer:

5.70456 slug

Step-by-step explanation:

Data provided in the question:

Dimensions of the room = 20 ft long, 15 ft wide, and 8 ft high

Now,

Volume of the room = 20 × 15 × 8

or

Volume of the room = 2400 ft³

we know,          

Density of air = 0.0023769 slug/ft³

Therefore,

Mass of air in the room = Volume × Density

= 0.0023769 × 2400

= 5.70456 slug

which equation models the same quadratic relationship as function f? f(x)=x^2+12x+4 a) y=(x-6)^2+40 b) y=(x+6)^2-32 c) y=(x-6)^2
motikmotik

9514 1404 393

Answer:

  b) y=(x+6)^2-32

Step-by-step explanation:

Add and subtract the square of half the x-coefficient to put into vertex form.

  f(x) = x^2 +12x +4 . . . . . given

  y = x^2 +12x +36 +4 -36 . . . . add and subtract (12/2)^2 = 36

  y = (x +6)^2 -32 . . . . . . . . . . . write in vertex form

F(x) = 2x^2 what is f(3)
katrin2010 [14]

Answer:

18 since f(3)=18

Step-by-step explanation:

f(x)=2x^2 is give as our function. To find f(3) we need to replace x with 3.

f(3)=2(3)^2   (Replaced x with 3.)

f(3)=2(9)   (Did 3^2 which was 3*3=9)

f(3)=18    (Did 2(9) which was 18)
