Answer:
-6125
Step-by-step explanation:
negative 78 squared = -6084
-6084 + 3 - 9 = -6090
-6090 - 5 squared minus 6 minus 4 = --6125
I got confused by "8th" and "a minus" do you mean 3a, and 6a?
Answer:
x = 4
CB = 28
Step-by-step explanation:
In triangle ABC,
AB = CB..... (given)
Therefore,
7x = 5x + 8
7x - 5x = 8
2x = 8
x = 8/2
x = 4
CB = 5x + 8 = 5*4 + 8 = 20 + 8 = 28
Answer:

Step-by-step explanation:
The given quadratic trinomial is 
Where a=6, b=-13 and c=-5

The factors of -30 that add up to -13 are -15,2
We split the middle term to get:

Factor by grouping:

These completely factors to:

The first thing you want to do is factor out 13. It can ether be (1, 12), (2, 11), (3, 10), (4, 9), (5, 8), or (6, 7). In this case, it says the difference of the two numbers is 3, so you subtract the two numbers 8 and 5 to get three. Your answer is 8 and 5
