Answer:

  Perimeter of the rectangle  = 6 x +20

 Perimeter of the rectangle  = 0 x² + 6 x + 20

Step-by-step explanation:

Step(i):-

Given that the length of the rectangle = 2x +3

Given that the width of the rectangle = x +7

Perimeter of the rectangle   = 2(length + width)

Step(ii):-            

  Perimeter of the rectangle   = 2(length + width)

                                                  = 2(2 x +3 + x+7)

                                                 =  4x +6+2x+14

                                                 = 6 x +20        

Final answer:-

 Perimeter of the rectangle  = 6 x +20

 Perimeter of the rectangle  = o x² + 6 x + 20

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of

amount of peas picked by Rim

Answers

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of  amount of pears picked by Kim.

Solution:

We know that,

[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]

[tex]\%\text{ increase}=\dfrac{37}{25}\times 10[/tex]

[tex]\%\text{ increase}=\dfrac{370}{25}[/tex]

[tex]\%\text{ increase}=14.8[/tex]

Therefore, the percentage increase of  amount of pears picked by Kim is 14.8%.

What is the commutative property? (Please don't copy and paste from go.ogle I need a good explanation)

Answers

Answer:

it basically means that the order in how you multiply doesnt matter. so wether u type 5 x 4 or 4 x 5 in ur calculator, you'll get the same answer either way. this works for when you want to multiply and divide, but not when you wanna subtract or divide.

Step-by-step explanation:

its basically a property that says that if you wanna swap the numbers/variables that are on one side of this specific type of equation (multiplication and addition), you can!

Answer:

yooo

Step-by-step explanation:

the communitive property  is when you have the same number or same equation but just reverse it. For example, (5x+67) with the communitive property could be (67+5x). Its just the equation you are given but reversed and since they are the same numbers, you will get the same answer either way you do the problem, hope this helps you lol.

Answer: what r u supposed to figure out

Step-by-step explanation:

Answer:

See below

Step-by-step explanation:

Given is the piecewise function.

It has three different pieces.

The first piecef(x) = 2, with x ≤ -2

Plot the point (-2,2) and draw a horizontal line to the left from this point

The second piecef(x) = 1/2x + 3, at the interval -2<x≤1

Plot two border points at x = -2 and x = 1:

f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)

and

f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)

Connect these two points with a line segment

The third piecef(x) = -7/8x + 35/8, at x > 1

Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)

f(1) = -7/8*1 + 35/8 = 28/8 = 3.5

and

f(5) = -7/8*5 + 35/8 = 0

Connect the two points (1, 3.5) and (5, 0) and extend the line to the right

Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.

Answer:

Maybe  -3

Step-by-step explanation:

I am not 100% sure but it is better than nothing,

since 3+3=6 I think after 3 is 6, and after 6 is 9. I think that because the more right the line goes you add  3 to every move. So therefore, 3-3=0, and 0-3= -3
