Question

Hey guys i need some help with a few questions please!
1)Find the degree of the monomial 6p3q2

2)Simplify (7t2 + 9) + (6t2 + 8).

3)Simplify (2z – 3)2

Answer 1

the exponents on 6p^3q^2 are 3 and 2. Add them to get 3+2 = 5

So the degree of 6p^3q^2 is 5

Answer 2

thanks

Answer 3

for #2

remove the parenthesis and combine like terms

Answer 4

one pair of like terms is

7t^2 and 6t^2 and they add to 13t^2

Answer 5

For number 2 these are the possible answers

a) t2 + 1
b) 13t2 + 17
c) 13t4 +17
d) 42t2 + 72

Answer 6

do you see how 6t^2 + 7t^2 = 13t^2 ?

Answer 7

yes

Answer 8

you add the like terms right?

Answer 9

exactly

Answer 10

the other pair of like terms are 9 and 8

they add to 9+8 = 17

Answer 11

thank you

Answer 12

for the last one, you would use the FOIL rule since

(2z – 3)^2 = (2z – 3)(2z – 3)

Answer 13

alright

Answer 14

4z2 – 9
4z2 – 9z
4z2 – 12z – 9
4z2 – 12z + 9

are the possible answers

Answer 15

using the FOIL rule, what do you get

Answer 16

nothing

Answer 17

not quite

Answer 18

(2z – 3)(2z – 3) = 2z(2z – 3) - 3(2z – 3)

Now use the distributive property to distribute out 2z(2z – 3) - 3(2z – 3)

Answer 19

ok

Answer 20

the answer is NOT choice A

Answer 21

2z(2z – 3) - 3(2z – 3)

4z^2 - 6z - 6z + 9
