4b - 2c is an expression, which is equal to 2(2b - c)
2c + 3
a + 7b + 2c
4c-7 = 2c+11 4c-2c = 11+7 2c = 18 c = 9
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
They are terms of an algebraic expression that can be simplified to: 2b+2c
4a*2c=8ac
4b - 2c is an expression, which is equal to 2(2b - c)
42
42 and 2c such that they are separated by a addition sign. Now, the term 2c is a variable term such that it is obtained when 2 is multiplied with the variable c. Hence, 2 is the coefficient of the expression.
The expression is 5d+2c and the unknown variables are d and c
-4
4ac + 2ad + 2bc +bd = 2a*(2c + d) + b*(2c + d) = (2c + d)*(2a + b)
In its most simplified form: = 12abc + 8bc - 20ab = 4b(3ac + 2c - 5a) = 4b[(c + 5/3)(3a + 2) - 10/3]
2c + 3
It is 9
(2a + b)(2c + d).
