Hello!

There are two ways to solve this.

First we can find the answer of the whole square, including the gap in the middle. This gives us 120. Now, if we subtract the area of the white rectangle (the part that doesn't exist), we get 106 m.

Just to verify, we can split the polygon into three polygons by splitting it with two lines, each bordering the edges of the white rectangle this gives us 48+48+10
This gives us 106, which matches our original answer.

This means that the area of the figure is 106 m².

I hope this helps!

Hi there!

Let's break this figure up into three rectangles. Two are congruent and one is smaller. 

The area of the larger rectangles:
2(4 x 12) = 96 

Area of the smaller rectangle:
2 x 5 = 10

Lastly, we'll add the areas together:
96 + 10 = 106

Area: 106 meters^2

Hope this helps!! :)

3y – 6x = 3 y = 2x + 1
Keith_Richards [23]

Answer:

infinite solutions along the line y = 2x+1

Step-by-step explanation:

3y – 6x = 3

y = 2x + 1

Replace y in the first equation with the second equation

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

6x +3 -6x = 3

3=3

This is always true so there are infinite solutions along the line y = 2x+1

23+8-(14-(7-2+3) step by step
Snowcat [4.5K]

Step 1: Do the most inner parenthesis (7-2+3) = 5 + 3 = 8.

23+8-(14-8)

Step 2: Do the next parenthesis (14-8) = 6

23+8-6

23+8 = 31

31 - 6 = 25

So, 25 is your answer!

A pretzel company calculated that there is a mean of 75.4 broken pretzels in each production run with a standard deviation of 5.
Snowcat [4.5K]

Answer:

P [ Z < 66 ]  = 35,15 %

Step-by-step explanation:

Normal Distribution

Population mean μ₀  = 75,4

Standard deviation  σ = 5,2

Then:

P [ Z < 66 ]  =  ( 66 - 75,4 ) / 5,2

P [ Z < 66 ]  = - 9,4 / 5,2

P [ Z < 66 ]  = - 1,81

In z-table we look for the reciprocate area for that  z score and find

P [ Z < 66 ]  = 0,3515

P [ Z < 66 ]  = 35,15 %

Simplify fully: X^2+3x-4/ 2x^2-5x+3
sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step  1  :

           2

Simplify   —

           1

Equation at the end of step  1  :

 ((((x2)+3x)-(2•x2))-5x)+3

Step  2  :

Equation at the end of step  2  :

 ((((x2) +  3x) -  2x2) -  5x) +  3

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  -x2 - 2x + 3  =   -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2     Factoring  x2 + 2x - 3

The first term is,  x2  its coefficient is  1 .

The middle term is,  +2x  its coefficient is  2 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   2 .

     -3    +    1    =    -2

     -1    +    3    =    2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  3

                    x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (x+3)  •  (x-1)

            Which is the desired factorization

Final result :

 (-x - 3) • (x - 1)
