Answer

The expression represented the perimeter of a rectangle be 12x -8 units .

Reason

Formula

Perimeter of  rectangle = 2× (length + breadth)

As shown in the diagram

Length = (3x-1) units

Breadth = (3x-3) units

Put this in the formula

Perimeter of rectangle = 2 × (3x - 1 + 3x - 3)

                                     = 2× (6x - 4)

                                     = 12x -8 units

Hence Proved

A tree 7ft tall grows an average pf 6in each year. which equation models the trees height h after x years?
sergejj [24]

Answer:

A)  h=0.5x+7

Step-by-step explanation:

given

initial height = 7 feet

growth rate = 6 in = 0.5 feet / year

let # of growing years = x

For a linear growth rate:

height after x years, h = initial height + (# of growing years) * (growth rate)

substiuting the values above into this equation

h = 7 feet + (x years) * (0.5 feet/year)

or

h = 7 + 0.5x (rearranging)

h = 0.5x + 7

F (×)=-3×^3-2 g (×)=-3×-3 find (-3) and g (4)
monitta
We assume you mean
.. f(x) = -3*x^3 -2
.. g(x) = -3*x^-3

Then
.. f(-3) = -3*(-3)^3 -2 = -3*(-27) -2 = 81 -2 = 79

.. g(4) = -3*4^-3 = -3/64

It is helpful if you use ordinary lower-case letters for variables (except in some formulas where upper-case letters are used). The symbol "×" is used to signify multiplication, so leads to confusion when you try to use it for a variable. In plain text, the exponentiation operator is a caret (^), so x^2 means "x squared", for example. If the exponent is supposed to include an arithmetic operation, then it needs to be enclosed in parentheses, x^(3y-4), for example.

3. Jorge used 2 packs of pencils in the first 1/3 of the year. At what rate is Jorge using pencils?​
ANTONII [103]

Answer:

Jorge is using pencils at a rate of 6 packs a year or a rate of 2 packs every four months.

Step-by-step explanation:

1/3 of a year is four months so that would be 2 packs every four months and if you multiply that by three you’d get 12 month, or one year, and 6 packs of pencils.
