Answer:

$\frac{2}{5}±\frac{\sqrt{17}}{5}$

Step-by-step explanation:

$(5x-2)^2=17 \\ 5x-2=±\sqrt{17} \\ 5x = 2 ± \sqrt{17} \\ x=\frac{2}{5}± \frac{\sqrt{17}}{5}$

Don't mind the $±$

If (x-2) is a factor of x^3+kx^2 +12x-8 then k=?

AURORKA [14]

Answer:

k = - 6

Step-by-step explanation:

Since (x - 2) is a factor then x = 2 is a root

Substitute x = 2 into the polynomial and equate to zero, that is

2³ + k(2)² + 12(2) - 8 = 0

8 + 4k + 24 - 8 = 0

4k + 24 = 0 ( subtract 24 from both sides )

4k = - 24 ( divide both sides by 4 )

k = - 6

determina la medida de cada uno de los angulos del triángulo ABC si se conoce que (3x+1)° (3x+4)° y (2x-1)°

Triss [41]

Answer:

∠A=67°

∠B=70°

∠C=43°

Step-by-step explanation:

The correct question in English is

Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

substitute the given values

$(3x+1)\°+(3x+4)\°+(2x-1)\°=180\°$

solve for x

$(8x+4)\°=180\°$

$8x=180-4$

$x=22$

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°
