Answer:
Multiplying and simplifying the term 
we get 
Option C is correct option.
Step-by-step explanation:
We need to multiply and simplify:
Simplifying the term:
While multiplying, the variables with same bases are multiplied: 
In the given question only x^2 and x^4 are variables with same bases, So we get:
So, multiplying and simplifying the term we get
Option C is correct option.
Answer:
255
Step-by-step explanation:
12x^(2) + 39x + 30
x = 3
Substitute in"3" for "x" and solve;
12(3)^(2) + 39(3) + 30
= 12 * 9 + 117 + 30
= 108 + 117 + 30
= 255
Answer:
-12+l4-72l
Step-by-step explanation: i hope this helps
We must look at each equation and pick out which property matches with the choices
For the equation:
5(8+3)=5*8+5*3
The property is
Distributive Property
For the equation:
4x+(5x+3)=9x+3
The property is
Commutative property of Addition
For the equation:
a+b=b+a
The property is
Associative Property of Addition
Answer:
Step-by-step explanation:
commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
