Answer: 32
Step-by-step explanation:
128 divided by 4 is 32 so u get 32 and 4 and multiply it and you get 32.
A = 2lw + 2lh + 2hw
A = 2(12)(3) + 2(12)(5) + 2(5)(3)
A = 72 + 120 + 30
A = 222 cm squared
Hope this helps!! :)

Answer:
Step-by-step explanation:
1). 

Comparing exponents on both the sides.
x² + 2x = -1
x² + 2x + 1 = 0
(x + 1)² = 0
x = -1
2). 


By comparing exponents,
x - 3 = 3(x + 1)
x - 3 = 3x + 3
3x - x = 3 + 3
2x = 6
x = 3
3). 

By comparing exponents,

5 - k = 2(3 - k)
5 - k = 6 - 2k
2k - k = 6 - 5
k = 1
4). 


By comparing exponents,
x + 3 = 3(2x + 6)
x + 3 = 6x + 18
6x - x = 3 - 18
5x = - 15
x = -3
5). 

x - 2 = 0
x = 2
