Can someone please help me

Answer:

y = -5/3x -7

Step-by-step explanation:

If lines are parallel they have the same slope m = -5/3. Just need to figure out the new y-intercept going through the point (-9, 8).

y = mx + b

8 = -5/3(-9) + b

8 = 15 + b

b = -7

Now use m and b to form new equation of parallel line.

y = mx + b

y = -5/3x -7

find the area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long. Round your answer to the nearest tent

OLga [1]

Answer:

The area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²

Step-by-step explanation:

Given : A regular hexagon with an apothem 10.4 yards long and side 12 yards long.

We have to find the area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long.

Since, the Given hexagon is a regular hexagon.

So, each side make equal angle with mid point.

Thus, Area of each triangle = $\frac{1}{2} \times base \times height$

base = 12 yards

height = 10.4 yards.

Thus, Area of each triangle = $\frac{1}{2} \times 12 \times 10.4=62.4$

Since, there are 6 triangles.

so area of hexagon = 6 × Area of triangle

area of hexagon = 6 × 62.4 = 124.8 yards²

Thus, The area of a regular hexagon with an apothem 10.4 yards long and side 12 yards long is 124.80 yards²
