Hello there i hope you are having a great day :) Your question: A certain television is advertised as a 50-inch TV (the diagonal length). If the width of the TV is 14 inches, how many inches tall is the TV?
So you would need to used the Pythagorean theorem that would be
c^2 = a^2 + b^2
So this would equal letter C as The hypotenuse of the right angle and also letter A and B are the stands on the triangle so C would equal 50 inches and A and B would equal 14 inches.
Then the Hard bit so you would be,
1) a^2 = c^2 - b^2
2) a = √c^2 - b^2
3) a = 50^2 - 14^2
4) a = √ 2,500 - 196
5) a = √2,304
6) A = 26
So the answer would be 26 Hopefully ❤
Answer:
how dose this kid earn!?
Step-by-step explanation:idk
Multiply, and Divide
2/ 2 - 15i
2(2 + 15i)/ (2 - 15i) * 2 + 15i
= ( 4 + 30i)/ (4 + 225)
= (4 + 30i )/ 229
Hence; 2/ 2 - 15i
= 4/ 229 + 30i/ 229
Therefore, Letter Choice (D); is your answer 4/229 + 30i/229
Hope that helps!!!!
Answer:
The quadratic equation is (x + 3)(x + 4) = 5
Step-by-step explanation:
If the degree of a polynomial is two then the polynomial is known as a quadratic.
Now, in the given equations we see which polynomial has a degree 2.
Simplify the first equation
Degree is 3 and hence it is not a quadratic.
Take 2nd equation
Degree is 1 and hence it is not a quadratic.
Finally, we simplify the third equation
Apply FOIL method to simplify the left hand side
Degree is 2 and hence it is a quadratic equation.
