Two students factored 2x^2 + 6x - 20. Leuko said that the factorization was (2x - 4)(x + 5). Ray gave the factorization as (x -

2)(2x + 10). Confirm that both of these factorizations are correct. Then explain why they are not complete.

Answer:

See explanation

Step-by-step explanation:

If you FOIL both of them, you see that they are both correct, but they both need to factor out a 2 and then they will both have the same thing.

Answer: To confirm the equations to be equal with the parent function we do as follows:

(2x – 4)(x + 5) = 2x^2 + 10x - 4x - 20 = 2x^2 + 6x -20

(x – 2)(2x + 10) = 2x^2 +10x - 4x -20 = 2x^2 +6x - 20

Points B, D, and Fare midpoints of the sides of angle ACE. EC = 39 and DF = 18. Find AC
Dmitry [639]

Answer: Line AC = 36

Step-by-step explanation: The first and most important clue is the fact that points B, D and F are midpoints of the triangle ACE. What this tells us is that point B divides line AC into two equal sides. Likewise points D and F. If point D divides line EC into two equal sides, then line ED equals

39/2 = 19.5

Also, triangle FED is similar to triangle AEC. Since ED is half of EC, and FE is half of AE. Therefore in triangles FED and AEC,

FD/ED = AC/EC

18/19.5 = AC/39

By cross multiplication we now have

(18 x 39)/19.5 = AC

702/19.5 = AC

36 = AC

Therefore line AC = 36
