Find value of 2x+2y if x+2y = 6 and x+y = 10

Mathematics

AleksAgata [21]1 year ago
5 0

Step-by-step explanation:

x + 2y = 6 \:  \: equ1 \\ x + y = 10 \:  \: equ2

From equ2,

x = 10 - y

Substituting the value of x in equ1,

(10 - y) + 2y = 6

Collect like terms

y=6-10

y = - 4

Substituting the value if y in equ2,

x+y=10

x+(-4)=10

x-4=10

x=10+4

x=14

Therefore, 2x+2y

2(14) + 2(-4)

28 - 8

=20

What is the smallest and largest perimeter of a polygon with an area of 20?
DENIUS [597]

Answer:

The polygon with the smallest perimeter is the megagon

The polygon with the largest perimeter is the triangle

Step-by-step explanation:

An equilateral triangle with area = 20 has

0.5× a²×sin60 = 20

a= 6.796

Hence, perimeter = 20.39

A square of area 20 has perimeter= 4×√20 = 17.9

A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05

Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases

Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.
