If the area of a rectangular garden is 45x2−12x square meters, and it has a length of 3x meters, what is its width?
nikitadnepr [17]

Answer:

  (9x -4) meters

Step-by-step explanation:

The relationship between area, length, and width is ...

  area = length × width

Dividing by length gives ...

  width = area/length

Filling in the given expressions, we have ...

  w=\dfrac{45x^2-12x}{3x}=\dfrac{45x^2}{3x}-\dfrac{12x}{3x}=9x-4

The width of the garden is 9x-4 meters.

Determine if the following sets of quadratics are equivalent. Choose true or false. x 2 - 10x + 14 = 0 and (2x - 10)2 = 156 (x -
Sholpan [36]
We have to determine if the sets of quadratics are equivalent:
A ) x² - 10 x - 14 = 0  and ( 2 x - 10 )² = 156
( 2 x - 10 )² - 156 = 0
4 x² - 40 x + 100 - 156 = 0
4 x² - 40 x - 56 = 0 / : 4
x² - 10 x - 14 = 0           T ( True )
B ) ( x - 10 )² = 68  and x² - 20 x = - 32
( x - 10 )² = 68
x² - 20 x + 100 = 68
x² - 20 x = 68 - 100
x² - 20 x = - 32              T ( True )
C ) x² - 6 x = 247 and ( x - 3 )² = 256
( x - 3 )² = 256
x² - 6 x + 9 = 256
x² - 6 x = 247              T ( True )
D ) ( x + 5 )² = 65  and   x² = 90 - 10 x
( x + 5 )² = 65
x² + 10 x + 25 = 65
x² = 65 - 25 - 10 x
x² = 40 - 10 x                F ( False )

What is the answer for this using substitution?
damaskus [11]

9514 1404 393

Answer:

  (x, y) = (2, -2)

Step-by-step explanation:

We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".

From the second equation, ...

  3y = 5x -16

Substituting into the first equation, ...

  2x +(5x -16) = -2

  7x = 14 . . . . . . . . . add 16

  x = 2 . . . . . . . . . .  divide by 7

Using our equation for y, we get ...

  3y = 5(2) -16 = -6

  y = -2 . . . . . . . . . divide by 3

The solution is (x, y) = (2, -2).
