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

i think asking google will you get the answer to that question
