The following octagon is formed by removing four congruent right triangles from a rectangle. What is the total area of the octag

rewona [7]

To find the total area of the octagon you can find the area of the rectangle that is created by the entire figure and subtract the areas of the four congruent right triangles.

(10 cm x 6 cm) - [4(1/2 x 2 x 2)]
60 cm² -8 cm² = 52 cm²

The total area of the octagon is 52 cm².

8(2n - 5) = 3(6n - 2)

joja [24]

Answer:

n=-17

Step-by-step explanation:

8(2n-5)=3(6n-2)

1) Distributive property

16x-40=18x-6

16x−40=18x−6

2) Subtract 16x16x from both sides.

-40=18x-6-16x

−40=18x−6−16x

3) Simplify 18x-6-16x18x−6−16x to 2x-62x−6.

-40=2x-6

−40=2x−6

4) Add 66 to both sides.

-40+6=2x

−40+6=2x

5) Simplify -40+6−40+6 to -34−34.

-34=2x

−34=2x

6) Divide both sides by 22.

-\frac{34}{2}=x

−

7) Simplify \frac{34}{2}

to 17

−17=x

8) Switch sides.

x=−17

51.24 * 7.18 round each factor to its greatest place

mezya [45]

Answer:by mathatube

Step-by-step explanation:

What does greatest place value mean?

THE GREATEST OR HIGHEST PLACE VALUE IS THE DIGIT FARTHEST TO THE LEFT IN A NUMBER. IT COULD BE ANY NUMBER EXCEPT ZERO.

LOOK AT THE NUMBER 3654. The 3 is the greatest or highest place value number because it is the digit farthest to the left. The 3 is in the thousands place.

Look at the number again with a zero. 03654. The 3 is still the largest place value number because zero does not count.

Following the rules for Rounding

After finding the greatest place value number you can use the rules for rounding and round the number.

Example 1: round 24,356 the greatest place value.

Look to the right of the number in the ten

thousands place. It's a 4, so Round down.

24,356 is rounded to 20,000 because the highest

place value of that number is in the ten thousand

place.

Example-2: round 8,636 to the greatest place value.

8 is the number farthest to the left so it is the greatest place value number and it is in the thousands place

So look to the right of the number in the thousands

place. It's a 6, so round up.

8,636 is rounded up to 9,000 because the highest place value of that number is the 8 in the thousands place.
