Answer:
A=384 
Step-by-step explanation:
A =2(wl+hl+hw)
A=2(8*8+8*8+8*8)
A=2(64+64+64)
A=2(192)
A=384
45 = 3×3×5
54 = 2×3×3×3
Two number : 3,3
So, the GCD of 45,54 is 3×3= 9

Answer:
28 bikes are blue
Step-by-step explanation:
Set up the ratio:
Blue : Black
4 : 5
Find the total # of bikes in the ratio:
4 + 5 = 9
Find the relationship between 63 and 9:
63/9 = 7
Multiply both sides of the ratio by 7:
4(7) = 28
5(7) = 35
28 : 35
Therefore, the number of blue bikes is 28.
Let's group the cubic function:

.
The first two roots are

however to find the last two roots we need to solve the square equation:

. Now we know the discriminator, using the discriminator we're able to find the roots of the equation:

. The roots of the square equation are

and

.
The roots of the cubic function are

,

and
