Answer:
Perimeter =<em>14x+10</em>
<em>Area =</em> =+17x+6
Step-by-step explanation:
Area of a rectangle=Length *width
=(3x+2)(4x+3)
=3x(4x+3)+2(4x+3)
=+9x+8x+6
=+17x+6
- Then find x using quadratic equation and substitute the values
Perimeter of a rectangle =2(length +width)
=2(3x+2+4x+3)
=6x+4+8x+6
=<em>14x+10</em>

Answer:
Step-by-step explanation:
The function d(x) takes a value of x in degrees centigrade and provides the number of degrees that a container of water at that temperature x is far from the boiling point of water.
The function f(d) takes a value d in degrees centigrade and returns a value d(x) in degrees fahrenheit.
Therefore, by doing f(d(x)) we are introducing the function d(x) within the function f(d).
So the range of d(x) now is the domain of f(d(x))
This means that the function f(d(x)) shows the <em>number of degrees Fahrenheit</em> that a water container at a<em> temperature x in degrees Celsius</em> is far from the boiling point of water.
Answer:
900 g
Step-by-step explanation:
let e be extension and w be weight
given e varies directly as w then the equation relating them is
e = kw ← k is the constant of variation
to find k use the condition w = 150 , e = 2.9 , then
2.9 = 150k ( divide both sides by 150 )
= k , that is
k =
e = w ← equation of variation
when e = 17.4 , then
17.4 = w ( multiply both sides by 1500 )
26100 = 29w ( divide both sides by 29 )
900 = w
