Answer:
6x-15
Step-by-step explanation:
First plug in 3x-9 for x
2(3x-9) +3
Multiply 2 by (3x-9)
2(3x-9)=6x-18
add 3
6x-18+3=6x-15
hope this helps :)
Answer:
1/6
Step-by-step explanation:
I guess we are to assume each is equally likely. There a 6 possible outcomes and one D so the answer is 1/6
Step 1: simplify
[3.4 ( 6 x + 2 ) +3] + 4 p -3 x
Pemdas!
6x+2=8x
3.4+3=6.4
6.4+8x=14.4
14.4x+4p=18.4xp+3= 21.4xpx
x=8
p=18.4
Other x = 21.4
Answer:
B) -125a^11
Step-by-step explanation:
(-5a^2)^3·a^5 = (-5)^3·a^6·a^5
= (-5)^3·a^(2·3)·a^5
= (-5)^3·a^6·a^5
= -125·a^(6+5)
= -125·a^11 . . . . matches choice B
_____
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
