Answer 1

Answer:

Answer:

Step-by-step explanation:

y = mx + b

Take any two points and set up 2 equations with 2 unknowns.

I'll start with the first two

y = 4x + b

410 = 4x + b (1)

440 = 6x + b (2)

Subtract (1) from (2)

440 = 6x + b

410 = 4x + b Subtract

30 = 2x Divide by 2

30/2 = 2x/2

x = 15

440 = 6(x) + b

440 = 6*15 + b

440 = 90 + b

b = 350

Now here is what you found.

Josie bought a new mirror. The mirror has 5 sides. What is the shape of the mirror? Hexagon B. C. D. Square Pentagon Heptagon 18. The perimeter of a church window is 80 inches. If the window is in the shape of a square, what is the length of each side of the window? A. B. C. D. 20 inches 40 inches 15 inches 60 inches

Answers

The mirror has 5 sides. Its shape is a pentagon. Penta means 5.

Perimeter of a church window is 80 inches. If the window is square shaped, its length of each side is 20 inches.

80 inches / 4 sides = 20 inches.

The shape of the mirror is Pentagon.

18. the length of each side of the church window is 20 inches, option A is correct.

Josie's mirror has 5 sides, which means it is a polygon with five edges.

The specific term used to describe a polygon with five sides is a pentagon.

A pentagon is a geometric shape with five sides and five angles. Each side of a regular pentagon is of equal length, and each interior angle measures 108 degrees.

In the case of Josie's mirror, since it has 5 sides, it is referred to as a pentagon.

18. Given that the church window has a perimeter of 80 inches and it is in the shape of a square.

We can find the length of each side by dividing the perimeter by 4 (since a square has four equal sides).

Perimeter = 4 × Length of each side

80 inches = 4 × Length of each side

Dividing both sides by 4:

Length of each side = 80 inches / 4

= 20 inches

Therefore, the length of each side of the church window is 20 inches.
