You would use d) power of a power because:
(x^4)^9
= (x^(4*(9))
= x^36
Answer:
Step-by-step explanation:
1)
?/10 =4/5
?/5×2 =4/5
4×2/5×2 =8/10 ... the number is : 8
2)
?/4 = 11/4....the number is : 11
I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a
