Observe the expression below and select the true statement (s). 2 (a+1) + 4b+3

a. The "4" in the second term is a coefficient.

b. The "a" in the first term is a factor.

c. The " (a + 1) " in the first term is a factor.

d. The "1" in the first term is a coefficient.

e. The "b" in the second term is an exponent.

f. The "3" in the last term is a constant.

Step-by-step explanation:

Given expression is

2 (a+1) + 4b+3

Simplify to get

=2a+4b+5

So we find that 2 is a coefficient of a and 4 the coefficient of b and 5 the constant term

a) The "4" in the second term is a coeffiicient. - - True because b has coefficient 4

b) The "a" in the first term is a factor.--Not true because 2a only has a as factor and not the full expression

c) (a+1) is a factor is true as I term has 2 and a+1 as factors

d) 1 is a coefficient - - Not true because coefficient here is 2

e) The "b" is not an exponent of II term but a factor

f) The "3" is a constant is true.
