Answer:
AB = 21
Step-by-step explanation:
So we have two triangles (AEB and ADC), and they're similar by AA
Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13
AB/AC = 7/13
Take AB as x aight
x/x+18 = 7/13
x=21
Rewrite 512x^3 as (8x)^3
(8x)^3 + 2197y^3
Rewrite 2197y^3 as (13y)^3
(8x)^3 + (13y)^3
Since both terms are perfect cubes, factor using the sum of cubes formula.
a^3 + b^3 = (a + b)(a^2 - ab + b^2) where a = 8x and b = 13y.
(8x + 13y)((8x)^2 - (8x)(13y) + (13y)^2)
Simplify
(8x + 13y)(64x^2 - 104xy + 169y^2)
Given :
New York City has a population of 8.55 million and 300 square mile area .
Manhattan has 1.64 million and 23 square miles area .
To Find :
How much greater is the population density of Manhattan than New York City.
Solution :
Population density of New York City :
Now ,
Therefore , population density of Manhattan is 
greater than New York City .
Hence , this is the required solution .
Answer: 4 feet
Step-by-step explanation:
An airplane is 180 feet long.
Blake makes a scale model of the airplane which is 1:45 of its actual size. To find the length of the airplane model goes thus:
= 1/45 × 180
= 4 feet
The model is 4 feet
