X^4/3-7x^2/3+10=0 what is x

MakcuM [25]

Solve for x:10 - (7 x^2)/3 + X^4/3 = 0
Subtract X^4/3 + 10 from both sides:-(7 x^2)/3 = -X^4/3 - 10
Multiply both sides by -3/7:x^2 = X^4/7 + 30/7
Take the square root of both sides:Answer: x = sqrt(X^4/7 + 30/7) or x = -sqrt(X^4/7 + 30/7)

Prove that the points (3,3),(3,7) and (9,3) are the vertices of a right triangle

Alinara [238K]

The points (3,3), (3,7) and (9,3) do not form a right angled triangle

Solution:

Given vertices of triangle are (3, 3) , (3, 7) and (9, 3)

Let the triangle be ABC

Let the vertices be,

A = (3, 3)

B = (3, 7)

C = (9, 3)

For a triangle to be right angled triangle, it must obey Pythagoras theorem

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

Therefore by above definition,

$AC^2 = AB^2 + BC^2$
