Mathematics

Answer:

1. 6 = x

2. 9 = n

3. -5 = y

4. 6 9⁄11 = k

5. -1 = m

6. -1 3⁄10 = y

Step-by-step explanation:

1. 4x - 8 = x + 10

2. ⅔n - 4 = 5n - 43

3. -2y - 24 = y - 9

4. 96 - 8k = 3k + 63

5. -5 + 8m = 2m - 11 [Distributive Property, combine like-terms, then solve for x]

6. For this one, I could not tell whether you wanted me to FOIL it or just treat it as multiplication, so I went with multiplication and got this: 18 - 10y = 31

For the rest, all you have to do is use the Distributive Property of Multiplication, then solve for x.

I am joyous to assist you anytime.

The diagram below shows a square inside a regular octagon. The apothem of the octagon is 15.69 units. To the nearest square unit

Musya8 [376]

Answer:

C. 647 square units

Step-by-step explanation:

To find the shaded area, subtract the area of the unshaded square from the area of the octagon.

Area of the octagon

$\textsf{Area of a regular polygon}=\dfrac{n\:l\:a}{2}$

where:

n = number of sides
l = length of one side
a = apothem

Given:

n = 8
l = 13
a = 15.69

Substitute the given values into the formula and solve for A:

$\implies \textsf{Area}=\sf \dfrac{8 \cdot 13 \cdot 15.69}{2}$

$\implies \textsf{Area}=\sf \dfrac{1631.76}{2}$

$\implies \textsf{Area}=\sf 815.88\:\:square \:units$

Area of the square

$\implies \textsf{Area}=\sf 13^2=169 \:\:square \:units$

Area of the shaded region

= area of the octagon - area of the square

= 815.88 - 169

= 646.88

= 647 square units (nearest square unit)

Is the triangle an equilateral triangle

solong [7]

It is not an equilateral triangle. To prove this, you must solve for x. I found x by setting 2x+5.2 = 3x+1.2 to get x=4. Then I plugged 4 into equation to see if they were equal. 2(4)+5.2= 13.2 and 3(4)+1.3=13.2 but 2(4)+6.2=14.2. This allows us to conclude that the triangle is not equilateral because all of the sides are NOT congruent. Hope that helped:))
