The given expression can be simplified to: 3b-a

7

2a+6b

When simplified it is: 2a+8b+4

p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c

5ab-2ab+4a-b+5b = 3ab+4a+4b

a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.

3(a + b) + a = 3a + 3b + a = 4a + 3b

a-b+a-b+2b+a = 4a

If a + b = 6, what is the value of 3a + 3b?

(2a - b)(2a + b)

This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)

3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)

4a + 3c - 2b - c + a - b = 5a - 3b + 2c

its B

It is simply as stated in the question. Without information about a or b, the expression cannot be simplified nor evaluated.

a(b+3)+b(b+3)

The expression is: (4a+b)/(2a-5b)

= a + b - 2

Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.

(a + 2 - b) (a + 2 + b)

1/4

-2a plus 3b

3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
