Solve this problem -x squared -40x- 80 =0
If r-squared = theta then r = Â±sqrt(theta)
x = 3 and y = 3 Form a simultaneous equation and solve by elimination.
x = 2
h = +11 and/or -11
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
Solve using the quadratic formula
If x squared -10 = 0 then x = the square root of 10
(x - 3)(x + 5)
Square root both sides and then x = 4
Not sure how to put it. The Pythagorean therom states that a squared plus b squared equals c squared. Aren't a, b and c all variables?
You have to put your heart into it!
do u mean solve 3 squared? if so it = 3x3x3 that's how u work it out so the answer would be 27. hope this helps :)
x = 25 / 3squared + 5
5b2 = 8b therefore 5b =8 therefore b = 1.6
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
X (x - 25) So X = 0 Or X = +25
Plot the straight line representing 2y = 12 - x. Plot the straight line representing 3y = x - 2 The coordinates of the point of intersection of these two lines is the solution to the simultaneous equations.
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.
