For 5-8, cis the hypotenuse of the right triangle ABC with sides a, b, c 5. a = 12, b = 5,c=?
6. a = 8,b=?,c= 10
7. a = 2,6 = 9,c=15
8. a = 12, b=3,c=?

Its due ! write an equation in which the quadratic expression 2x^2-2x 12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

What is the value of x? assume that the line is tangent to the circle.
