Answer:
-4x^2 -3x - 5
Step-by-step explanation:
-4x^2 + 2x - 5(1 + x)
Distribute
-4x^2 + 2x - 5 -5x
Combine like terms
-4x^2 -3x - 5
The answer is Every 15 seconds
3x+2y=12 |•2
6x+3y=21
6x+4y=24
6x+3y=21
0x+y=3
y=3; x=2
2/3 + n = 2n + 3 <== ur equation
2/3 - 3 = 2n - n
2/3 - 9/3 = n
-7/3 = n <== ur solution
or
2/3 + n = 2n + 3...multiply everything by common denominator of 3
2 + 3n = 6n + 9
2 - 9 = 6n - 3n
-7 = 3n
-7/3 = n
2^10=1024
(a^m)^n=a^(m*n)
------------------
(2^(10))^(-1/5)
=2^(-10/5)
=2^(-2)
=1/4 (As the inverse of 2^2 is 1/4)
