-8(1 + 5b) – 2(86 – 1) = 50
kati45 [8]

Answer:

b = -57/10

Step-by-step explanation:

Let's first distribute everything out:

-8(1 + 5b) = -8 * 1 + (-8) * 5b = -8 - 40b

2(86 - 1) = 2 * 85 = 170

So, we have:

-8 - 40b - 170 = 50

-40b - 178 = 50

-40b = 50 + 178 = 228

b = -228/40 = -57/10

Thus, the answer is b = -57/10.

Hope this helps!

Factor completely 5ab(x + 6) − 4(x + 6).
konstantin123 [22]
It seems like you've begun to apply the grouping method.

Because the two binomials in the parentheses are the same, we can rewrite this as

(5ab-4)(x+6)

(x+6) cannot be further factored. (5ab-4) cannot be further factored either.

Final answer: (5ab-4)(x+6)
