Solve by completing the square x^2-6x-4=0
Vesna [10]

Answer:

x = 3 ± \sqrt{13}

Step-by-step explanation:

x² - 6x - 4 = 0 ( add 4 to both sides )

x² - 6x = 4

To complete the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(- 3)x + 9 = 4 + 9

(x - 3)² = 13 ( take square root of both sides )

x - 3 = ± \sqrt{13} ( add 3 to both sides )

x = 3 ± \sqrt{13}

If a is half b , and b is twice c , then a:c=​
faust18 [17]

Answer: a/c = 1

a/b = 1/2 => a = 1/2 .b

b/c = 2 => c = 1/2 .b

=> a/c = (1/2.b)/(1/2.b) = 1

A right isosceles triangle has an area of 65cm^2. What's the length of each leg to the nearest tenth of a cm.
Andreas93 [3]

Well, we know that the legs of this triangle are equal, and we know
that the area of any triangle is  (1/2)(base)(height) .

Since this is a right triangle, we can set it down on one leg, and then
the other leg will be the height.  Then ...

    Area = (1/2) (base) (height)

             = (1/2) (leg) (leg)

    65 cm²  =  (1/2) (leg)²

Multiply each side by  2 :  130 cm²  =  (leg)²

Take the square root of each side:      leg = √130 cm²  =  11.402 cm

                                        rounded to the nearest tenth:    11.4 cm
