(05.03)Calculate the area of the irregular polygon shown below: Image of letter E with height of 12 and width of 7 and inside space of height of 5 and width of 6. All units are in inches. 24 square inches 44 square inches 54 square inches 84 square inches

Answers

Answer:

24 square inches

Step-by-step explanation:

We are given Image of letter E with height of 12 and width of 7

Inside space of height of 5 and width of 6

Initially calculate the area of rectangle ABKL = length *width = 12*7= 84 square inches

Now to get the area of given figure subtract the area of rectangle CDFE and HGJI from the rectangle ABKL

Area of CDEF = Area of HGJI because the length and width of the rectangles is same

Thus Area of CDEF = length *width =5*6 = 30 square inches

Thus the Area of HGJI = 30 square inches

Now subtract the area of both rectangles from the area of rectangle ABKL

⇒84-(30+30)

= 24 square inches .

Hence the area of given figure LETTER E = 24 square inches .

Consider the linear system of equations y=2/5x-1 and 2x-3y+1=0 graph the system of equations

Answers

We can see that the lines intersect at: (-5,-3)

Step-by-step explanation:

Given system of equations is:

$y = (2)/(5)x-1\ \ \ \ Eqn1\n2x-3y+1 = 0\ \ \ \ Eqn2$

Lets convert the second equation in the same form as the first equation

$2x-3y+1 = 0$

Adding 3y on both sides

$2x-3y+1+3y = 0+3y\n2x+1 = 3y\n3y= 2x+1$

Dividing both sides by 3

$(3y)/(3) = (2x+1)/(3)\ny = (2)/(3)x+(1)/(3)\n$

The graph of equation can be plotted using manual graphing or any online graphing calculator

We will use the Desmos online graphing calculator to graph the equations (Picture attached)

We can see that the lines intersect at: (-5,-3)

I need help solving (5-6x9+6)x9+3-85 I came up with -109. Is that right

Answers

Multiply −6 by 9 to get −54.(5−54+6)⋅9+3−85Subtract 54 from 5 to get −49.(−49+6)⋅9+3−85Add −49 and 6 to get −43.−43⋅9+3−85Multiply −43 by 9 to get −387.−387+3−85
Add −387 and 3 to get −384.−384−85Subtract 85 from −384 to get −469.−469

thats what i did to get -469. show your work for finding -109 and we can compare

So we have
(5-6x9+6)x9+3-85

So this is a oder of operation question, firstly you start with the brackets

(5-6x9+6)

B. Brackets
E. Exponents
D. Division
M. Multiplication
A. Addition
S. Subtraction

(5-6x9+6)

Multiplication first

6x9=54

Now we have
(5-56+6)

56+6=62

62-5=57

((57))

Now we have left

57x9+3-85
Start from multiplication

57x9=513

513+3= 516

516-85= 413

413
