To find the total area of the octagon, we need to find the area of the rectangle and subtract the areas of the four congruent right triangles that were removed.

Let's assume the length of the rectangle is L and the width is W.

The area of the rectangle is L * W.

The two smaller sides of the right triangle are congruent to the width of the rectangle, which is W. The hypotenuse of each right triangle is congruent to the length of the rectangle, which is L.

The area of a right triangle is (base * height) / 2. In this case, the base is W and the height is L.

So, the area of one right triangle is (W * L) / 2.

Since there are four congruent right triangles, the total area of the right triangles is 4 * (W * L) / 2 = 2 * (W * L).

Therefore, the total area of the octagon is (L * W) - 2 * (W * L).

The total area of the octagon = L * W - 2 * W * L.

We don't know the actual values of L and W, so we cannot calculate the exact area. However, we can simplify the expression.

The total area of the octagon = L * W - 2 * W * L = LW - 2WL = LW - 2WL = LW - 2WL = LW.

Therefore, the total area of the octagon is equal to the area of the rectangle.

Answer:

Both are right triangles so you can do 4*3= 12 and then 12/2= 6

then 6*8=48 and 48/2=24

24+6 =30!

Answer:

(2, - 5)

Step-by-step explanation:

The line y = -1 is horizontal: parallel to the y-axis.

The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:

Δy = 3 - ( - 1) = 4

When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change.  The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.

Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).

Hope this helps -----

The surface area that will be frosted with icing is 205in²

It will be equal to the sum between the top surface, which measures:

S = 13in*9in = 117 in²

And the four lateral sides, two of them measure:

s' = 2in*9in = 18in²

The other two measures:

s'' = 13in*2in = 26in²

Then the total surface area that must be frosted is:

SA = 117 in² + 2*( 18in²) + 2*(26in²) = 205 in²

So we conclude that the correct option is C.

The value of the mixed expression 2 x (12) x 3/2 will be 36.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2 x (12) x 3/2. the value of the expression will be calculated as below:-

E = 2 x (12) x 3/2.

E = 12 x 3

E = 36

Therefore, the value of the mixed expression 2 x (12) x 3/2 will be 36.

Answer:

B. 19

Step-by-step explanation:

35-16=19

This is a perfect square trinomial in the form a^2 - 2ab + b^2 = (a-b)^2. In this case, a = x and b = -3.

Another way you can look at it is to ask yourself "what two numbers multiply to 9 (last term) and add to -6 (middle coefficient)?". Those two numbers are -3 and -3

-3 plus -3 = -6

-3 times -3 = 9

So this is why x^2-6x+9 = (x-3)(x-3)

We can expand (x-3)(x-3) back out to get x^2-6x+9 again using the FOIL rule, distributive property, or the box method.

Answer:

C. (x-3)(x-3)

Step-by-step explanation:

x² - 6x + 9 = 0

x² - 3x - 3x + 9 = 0

x(x - 3) - 3(x - 3) = 0

(x - 3) (x - 3) = 0

Step-by-step explanation:

All the angles are 90°, so set 6y and 3x equal to 90, like so:

6y = 90

Divide both sides by 6:

y = 15

Solving for x:

3x = 90

Divide both sides by 3:

x = 30

Step-by-step explanation:

3) in parallelogram opposite angles are equal

6y=90

y=15

x=30

By definition it is not repeated multiplication

2)   (one-half) (one-half) (one-half)

By definition it is repeated multiplication

credit means that you can buy anything you want but your not spending your money but eventually you will have to pay it back

so she can use the dishwasher while paying for it over a period of time and she can buy the dishwasher even if she doesn't have the money now to pay for it.

if she pays it with cash then she's using her money with the credit you have to pay it over time and if you don't pay the credit you will be in BIGG trouble so pay it!!

hope it helped!! :D

She can receive a discount on the price if she uses credit instead of paying cash. She can buy the dishwasher even if she doesn't have the money now to pay for it. Hence, Option A and C are the correct options.

A loan is a form of credit where a lender allows another party (the borrower) the use of money or property for a specified period of time.

Why does credit that offers long-term advantages exist?

If those conditions are met, a long-term loan can reduce the impact on operational cash flow, allow a debtor to borrow at a lower interest rate, reduce investor interference, and assist a business in establishing its credit worthiness.

Short-term loans are thus preferred for working capital, such as payroll, inventory, and seasonal imbalances, whereas long-term loans are typically used to purchase fixed assets, such as equipment.

Credit cards are more widely accepted and, in general, faster to use than checks. Bill payments via credit card can be made automatically, combining multiple payments into a single one.

By using a credit card with a rewards programme, you could earn rewards such as free travel.

a. Okay, so you multiply the 4.7 and 2.9 together, and then add the exponents

13.63 * 10^10

But we are not done. There can only be one digit in front of the decimal point. So, you move the 13.63 back one place so 1.363. But we have to do this to both sides, so the answer is 1.363 * 10^11.

b. Now you divide the 5.8 and 2, and subtract the exponents.

2.9 * 10^-5

The negative exponent is fine in this case if you were wondering.

c. Expand the scientific notation to 1500, then add the 2491 and then put that in scientific notation is what I would do. You can also express 2491 in scientific notation and add them. Either way you will get 3.991 * 10^3

d. Same thing here except with subtraction. The answer is 6.5 * 10^-4.

Step-by-step explanation:

7.50(15) + 1.25x = 166.25

112.50 + 1.25x = 166.25

Subtract 112.50 from both sides

(112.50 - 112.50) + 1.25x = (166.25 - 112.50)

1.25x = 53.75

Divide 1.25 from both sides
