Givin the area of a square is 225 square feet, what is the length of each side
Romashka [77]
The area of a square is calculated by squaring the length of the sides (multiplying by itself).  Therefore, in order to find the length, you must find the square root of 225. 

The square root of 225 is 15.  Therefore, you length of each side is 15 feet. 


p.s. I don't know how old you are, but I would recommend trying to memorise your square numbers up to 17^{2} .  I know I found that incredibly useful when it came to my exams last year (GCSEs)

Please help ASAP! <br><br> Law of sines...
kirza4 [7]

Answer:

b = 35.00

Step-by-step explanation:

To make use of the Law of Sines, you need to know angle B. Of course, its value will make the sum of all angles be 180°, so it is ...

B = 180° -34.5° -29.8° = 115.7°

Then the law of sines tells you ...

b = sin(B)·a/sin(A) = 22·sin(115.7°)/sin(34.5°)

b = 35.00

The variables A, B, and C represent polynomials where A = x + 1, B = x2 + 2x − 1, and C = 2x. What is AB + C in simplest form? x
mylen [45]

Answer:

If you would like to write a * b + c in simplest form, you can do this using the following steps:a = x + 1b = x^2 + 2x - 1c = 2xa * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1The correct result would be x^3 + 3x^2 + 3x - 1.
