41/6-5/6 = 36/6
36/6= 6

So 5/6 would need to be subtracted to develop a fraction that divides to 6

What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to solve

professor190 [17]

Answer:

x=−41/20

Step-by-step explanation:

(2x+3)(2)+8(2x+3)+11=0

Step 1: Simplify both sides of the equation.

(2x+3)(2)+8(2x+3)+11=0

(2x)(2)+(3)(2)+(8)(2x)+(8)(3)+11=0(Distribute)

4x+6+16x+24+11=0

(4x+16x)+(6+24+11)=0(Combine Like Terms)

20x+41=0

20x+41=0

Step 2: Subtract 41 from both sides.

20x+41−41=0−41

20x=−41

Step 3: Divide both sides by 20.

20x/20=−41/20

x=−41/20

which of the following is the correct classification for triangle WXY given W(-7,1), X(0,-4) and Y(2,3)?

spin [16.1K]

Answer:

Scalene triangle

Step-by-step explanation:

Coordinates of the vertices of the triangle are,

W(-7, 1), X(0, -4) and Y(2, 3)

We will use the formula to get the distance between two points.

d = $\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

WX = $\sqrt{(-4-1)^2+(0+7)^2}$

= $\sqrt{74}$

WY = $\sqrt{(1-3)^2+(-7-2)^2}$

= $\sqrt{85}$

XY = $\sqrt{(3+4)^2+(2-0)^2}$

= $\sqrt{49+4}$

= $\sqrt{53}$

Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.

Find the zeros of the polynomial function f(x) = x2 – 12x + 20

PSYCHO15rus [73]

${f(x) = x^2 - 12x + 20 = x^2-2x-10x+20 = x(x-2)-10(x-2) = (x-2)(x-10)}$

f(x)=0

$(x-2)(x-10)=0$

$x-2=0 \ or \ x-10=0$

$x=2 \ or \ x=10$
