Question

Combine the like terms to simplify the expression.

7p2 + 9q2 + 4q2 – 4p

(Points : 4)
3p + 13q4
3p + 13q2
7p2 + 13q4 – 4p
7p2 + 13q2 – 4p

Which lists the even numbers between 1 and 19 in set notation?
(Points : 4)
{1, 3, 5, 7, 9, 11, 13, 15, 17, 19}
{2, 4, 6, 8, 10, 14, 16, 18}
{2, 4, 6, 8, 10, 12, 14, 16, 18}
{0, 2, 4, 6, 8, 10, 12, 14, 16, 18}

Answer 1

\[7p^2 + 9q^2 + 4q^2 – 4p\]
The first think to do is to identify the like terms,

Like terms have the same variables in them (letters) ; and the same amount in each.

Which two terms are like terms?

Answer 2

think* step

Answer 3

c

Answer 4

huh?

Answer 5

the answer to number 1 is c right

Answer 6

How did you get that?

Answer 7

What like terms did you combine?

Answer 8

9q+4q

Answer 9

its not C

Answer 10

The like terms are 9q^2 and 4q^2 (because the both have q^2's in them )

9q^2 + 4q^2 can be simplified by factoring out the common factor

= (9+4)q^2
= . . . q^2

Answer 11

so its D

Answer 12

@texaschic101 is it b

Answer 13

yes...first one is b

as far as the second question, which set has even numbers from 1 to 19 ?
Even numbers are 2,4,6,8..etc. You should be able to do this one.
