p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
If a + b = 6, what is the value of 3a + 3b?
= a + b - 2
a = 15.
3a(b+c)+2b(b+c)
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
The given expression can be simplified to: 3b-a
If a + b = 6, what is the value of 3a + 3b?
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)
a number
They are terms of an algebraic expression
7a-2b
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)
= a + b - 2
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
