Answer: 4w+3

Step-by-step explanation:

Let 'w' denotes the width of the rectangle.

Given : The length of a rectangle is \dfrac{3}{2}+w units.

Since , perimeter of rectangle = 2( length + width)

\Rightarrow\text{Perimeter}=2(\dfrac{3}{2}+w+w)\\\\\Rightarrow\text{Perimeter}=2(\dfrac{3}{2}+2w)\\\\\Rightarrow\text{Perimeter}= 2(\dfrac{3}{2})+2(2w)\\\\\Rightarrow\text{Perimeter}=3+4w

Hence, the expression that gives the perimeter of the rectangle in terms of its width  = 4w+3

<h2>Answer:</h2>

The quadratic function are:

 option: A   A)  y(y + 4) - y = 6

 Option: C   C.)  4b(b) = 0

<h2>Step-by-step explanation:</h2>

We know that the general equation of a quadratic equation in terms of a variable x is given by:

   ax^2+bx+c=0

A)

y(y + 4) - y = 6

On simplifying the terms we have:

   y^2+4y-y=6\\\\y^2+3y-6=0

Hence, option: A is correct.

B)

(3x + 2) + (6x - 1) = 0

(3x + 2) + (6x - 1) = 0\\\\i.e.\\\\3x+2+6x-1=0\\\\i.e.\\\\3x+6x+2-1=0\\\\i.e.\\\\9x+1=0

Hence, it is a linear equation.

Hence, option: B is incorrect.

C)

4b(b) = 0

it could also be written as:

4b^2=0

Hence, it is a quadratic equation.

Hence, option: C is correct.

D)

3a - 7 = 2(7a - 3)

3a-7 = 2(7a-3)\\\\i.e.\\\\3a-7=14a-6\\\\\\i.e.\\\\14a-6-3a+7=0\\\\i.e.\\\\14a-3a-6+7=0\\\\i.e.\\\\11a+1=0

which is again a linear equation.

Hence, option: D is incorrect.

F is the midpoint of EG If EF = x + 2 and FG = 2x - 6, find<br> FG
mezya [45]

Answer:

FG = 10

Step-by-step explanation:

EF = x + 2 ; FG = 2x - 6

F is the mid-point of EG. So, EF = FG

=  > x + 2 = 2x - 6

=  > 2x - x = 6 + 2

=  > x = 8

FG = 2×8 - 6 = 10

The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20

Step-by-step explanation:

Given as :

The total amount spend for soup = $ 20

The cost of Tomatoes = $ 2.50 per pound

The cost of Red peppers = $ 4 per pound

Let the quantity of tomatoes to be bought = T pound

The quantity of red peppers to be bought = R pound

So, According to question

$ 2.50 × T + $ 4 × R = $ 20

I.e The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20   . Answer
