Let x = length of segment EF.

Assume that
(a) line segments AD,  EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.

Then from similarity between geometric shapes, we can write
\frac{2.2}{x} = \frac{x}{4.8}
x^{2} =(2.2)(4.8)=10.56
x=3.2   (nearest tenth)

Answer: B. 3.2

Solve for x. Write both solutions, separated by a<br> comma.<br> 9x^2+ 3x – 2 = 0
kogti [31]

Answer:

x=1/3, x=-2/3

Step-by-step explanation:

9x^2 +6x -3x -2=0

6x and -3x add up to 3x. You need four terms to factor.

Then you factor=

3x(3x+2)-1(3x+2)=0

(3x-1)(3x+2)=0

Then you can make two equations

3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.

3x-1=0

3x=1

x=1/3

3x+2=0

3x=-2

x=-2/3

So your answers are x=1/3, x=-2/3

hope this helps!
