Pythagorean theorem (or however it is spelled)
a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse
3^2 + b^2 = 11^2
9 + b^2 = 121
b^2 = 121 - 9
b^2 = 112...take the square root of both sides, eliminating the ^2
b = square root of 112
b = 10.58 <=== the other leg of the triangle
Answer:
Is irrational
Step-by-step explanation:
Let be a rational number, and be an irrational number. If their sum were rational, say , then we'd have
but is the difference between two rational numbers, and thus a rational number. But it also equals , which is irrational by hypothesis. Since we have a contradiction, we conclude that the sum of a rational and an irrational can't be rational.
Answer:
x = 3 and x = 4
Step-by-step explanation:
3x - 4 + 4x - 8 = x^2
7x -12 = x^2
x^2 - 7x + 12 = 0
(-4)*(-3) = 12 and (-4)+(-3) = -7
(x-3)(x-4) = 0
x - 3 = 0. x = 3
x - 4 = 0. x = 4
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
