Using Communative Property, We can switch the equation around to make it look the same.
Answer:
The remaining solutions are -7 and 3.
Step-by-step explanation:
The synthetic division is shown in the attachment. After dividing the first two found factors from the polynomial, the remaining quadratic is ...
x^2 +4x -21 = 0
Its rational roots will be factors of -21, and the sum of their opposites will be 4. Knowing that 21 = 3·7, we can guess that the remaining roots are -7 and 3. The synthetic division confirms that. (A graph also confirms it.)
If

denotes the sum of the first

terms of a geometric series with first term

and common ratio

, then





Using summation notation, you have

In this case, you have

,

, and

. So the value of the sum is

Rounded to the nearest whole number, the answer would be 3.
Answer:
BD=7
ED=5
BE=7
AD=10
AE=5
Step-by-step explanation:
given CD = 7 you use that to find BD and BE because CD´s line length is the same as BD and BE
given BC = 5 you use that to find ED and AE and AD because BC is the same length as ED (they create the same triangle) and than given AE also equals 5 you add ED and AE to get AD
hope this helps
