Answer 3

3

Answer 4

1

Answer 5

its a constant

Answer 6

he wants the number of terms.

Answer 7

2 + a - b

so 3 terms

Answer 8

nope

Answer 9

@saifoo how much terms are here x+k+k^2+4

Answer 10

Four.

Answer 11

coz they cant be added.

Answer 12

so u r saying it depends on if there are consonants or variables?

Answer 13

a + 2a + b <----- 2 terms

no thats only one [k+k^2+4] is one term

Answer 15

there was no bracket before.

Answer 16

not needed

Answer 17

k+k^2+4 is one term

Answer 18

From Wikipedia
"In elementary mathematics, a term is either a single number or variable, or the product of several numbers or variables separated from another term by a + or - sign in an overall expression. For example, in
3 + 4x + 5yzw
3, 4x, and 5yzw are all terms."

Answer 19

Lol, but still. condused.

Answer 20

confused*

Answer 21

I would say 2 terms. They would want you to consider what's in parenthesis to be one term.

Answer 22

@Alchemista u r right

Answer 23

with every term there should be some variable to power ____

Answer 24

so:
2(x+2) is 1 term?

Answer 25

yes

Answer 26

:O

Answer 27

/and 2x+4 is 2 terms

Answer 28

@jahtoday there are 2 terms

Answer 29

yeah

Answer 30

2(x+2) the first 2 is a constant factor and the expression has two terms

Answer 31

The grammar for a mathematical expression can be defined using this CFG:

S-> T (+|-) T
T-> <term stuff> | S

Answer 32

so (x+2) is 1 term and x+2 is 2 terms then

Answer 33

(x+2) is a factor with two terms

Answer 34

I disagree. 2(x+2) is a single term. You aren't considering what the expanded form is.

Answer 35

so y is (a+b) 1 term???

Answer 36

Alchemista is right

Answer 37

(a+b) a is constant b is constant, constant +constant is a constant so one term

Answer 38

so x^3+x^2+x is three terms right?

Answer 39

or is that 1 term?

Answer 40

yes

Answer 41

3

Answer 42

so how did u kno that a and b in the original thing was constants and not variables?

Answer 43

thats a convention , all time u will take a,b,c,d,e,k as constants and x,y,z,u,v,w as variable if not stated

Answer 44

ok so ur saying its all equal to 1 number and thus 1 term got it thanx

Answer 45

yes wellcome most wellcome

Answer 46

okay so what is the answer
