The first thing you want to do in this equation is get rid of the parenthesis. Because 4-2 is added to (3b+6) you cannot distribute the 2. However, there is an invisible 1 next to the parenthesis, so you can use that. Additionally, I like to change subtraction to addition of a negative number. It makes things a little less confusing.
4+ -2 + 3b + 6
Now just combine the like terms.
4 + -2 = 2
6+ 2 = 8
So the simplified version of your problem is: 3b + 8
Answer: 1, 1&1/4, 3/2, 1&6/8
All you need to do is divide 291 by 7. If the quotient is a whole number, then 7 would be a factor of 291.
Let's test it out then, look at the picture attached.
As you can see in the picture attached, there is a remainder, so this would mean that 7 is not a factor of 291.
Answer:
b(10) = 76
Step-by-step explanation:
To find b(10) substitute n = 10 into the formula
b(10) = - 5 + 9(10 - 1) = - 5 + 9(9) = - 5 + 81 = 76
