For this case, we have that by definition, a perfect square trinomial, is a polynomial of three terms (also called trinomial) that results from squaring a binomial.

(a + b) ^ 2 = a ^ 2 + 2ab + b ^ 2\\(a-b) ^ 2 = a ^ 2-2ab + b ^ 2

We have:

4x ^ 2-20xy + 25y ^ 2\\(2x) ^ 2 = 4x ^ 2\\(5y) ^ 2 = 25y ^ 2

So:

2 * 5y * 2x = 20xy

So, 4x ^ 2-20xy + 25y ^ 2we can write it as:

(2x-5y) ^ 2

A portion of a hiking trail slopes upward at about a 6 angle. To the nearest tenth of a foot, what is the value of x, the distan
Firdavs [7]
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft

The nakagin capsule tower has 140 modules and is 14 stories high if the modules were divided evenly among the number of stories
Burka [1]
To determine the number of modules that is in each story, we simply divide the number of modules by the number of stories. 
                           = 140 / 14
Simplifying,
                           = 10 modules / story
Therefore, by even distribution we note that there are 10 modules per story.

kogti [31]

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50
