These questions are SOOO easy, but I just don't have a clue. (don't even know if they technically are algebra they are that easy).
x² - 8x - 20 =
(x+10) (x-2)
Thats what I got for that answer (lucky guess) but how do you know which side each sign goes on.. ie (x+10)(x-2) or (x+2) (x-10)??
Same problem with this question...
(x-6) (x-5) =
x² - 11x + 30
Answer:
Yes, a solution
Step-by-step explanation:
Plug -3 in for all the x's to see if it is a solution
6x + 5=5x + 8 +2x
6(-3)+5=5(-3)+8+2(-3)
Multiply on the left
-18+5=5(-3)+8+2(-3)
Add on the left
-13=5(-3)+8+2(-3)
Multiply on the right
-13= -15+8-6
Add on the right
-13=-7-6
-13=-13
Because they are equal, -3 is a solution
Hope this helps! :)

Answer:
B
Step-by-step explanation:
1. Lets focus on 55^5
55^5 = 11^5 * 5^5
2. now on 65
65 = 5 * 13
3. now on 9^15
9^15=(3^2)^15 = 3^30
4. combine all three parts
11^5 * 5^5 * 5 * 13 * 3^30 = 11^5*5^6*13*3^30
so our answer is B
