Answer:

5/8m - 3/8

Step-by-step explanation:

1/4 m + 3/4 m - 3/8m - 3/8

to combine m’s, change 1/4 to 2/8. And 3/4 to 6/8.

2/8 m + 6/8m - 3/8 m - 3/8

2/8+ 6/8- 3/8= 5/8

5/8m - 3/8

A regular hexagon has an apothem of 14. 7 inches and a perimeter of 101. 8 inches. What is the area of the hexagon?.

AleksAgata [21]

Answer:

748.23 in²

Step-by-step explanation:

<u>Area of a Regular Polygon</u>

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

where:

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

Given:

n = 6
l = 101.8 ÷ 6
a = 14.7

Substituting the given values into the formula and solving for A:

$\implies \textsf{A}=\dfrac{6 \cdot \dfrac{101.8}{6} \cdot 14.7}{2}$

$\implies \sf A=\dfrac{101.8 \cdot 14.7}{2}$

$\implies \sf A=\dfrac{1496.46}{2}$

$\implies \sf A=748.23$

Therefore, the area of the hexagon is 748.23 in²

5x+5y=0 <br> -8x+y=36<br> I need help with this.

zvonat [6]

First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4
