Answer:

13.5 is the next term

4, 6, 9, 13.5

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3/2

Answer:

45.5625

Step-by-step explanation:

The pattern seems to be x + (x/2) = y where x is the previous number and y is the next number.

4 + (4/2) = 6

6 + (6/2) = 9

therefore we continue the pattern. In doing so we get:

30.375 + (30.375/2) = 45.5625

Which of these is a correct step I construing an angle bisector?

olasank [31]

Answer:

1) Place the compass point at the vertex of the angle and open it to any width. Draw an arc that intersects of the sides of the angle.

2) Place the compass point at the one of the intersection points. Place the pencil at the other intersection point. This sets the compass with.

3) Draw an arc inside the angle.

4) Move the compass point to the intersection point on the other side of the angle being sure to keep the compass width the same. Draw a second arc inside the angle.

5) Make a point where the 2 arcs intersect the angle. Use a straight edge to draw a ray from the vertex of the angle through the point.

(x+1)^2+(x-1)^2-2x(x+2)=0

antoniya [11.8K]

Answer:

x = 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$(x+1)^2+(x-1)^2-2x(x+2)=0$
$x^2 + 2x + 1 + x^2 - 2x + 1 -2x^2 -4x = 0$
$(x^2 + x^2-2x^2) + (2x-2x-4x)+(1+1)=0$
$-4x + 2 = 0$

Step 2: Subtract 2 from both sides.

$-4x + 2 - 2 = 0 - 2$
$-4x = -2$

Step 3: Divide both sides by -4.

$\frac{-4x}{-4} = \frac{-2}{-4}$
$x = \frac{1}{2}$
