Step-by-step explanation:
In my opinion by looking at the photograph I think its 6 in my opinion sorry if I'm wrong
One formula for the lateral area is
A = 2(LW + H(L+W))
Filling in the given numbers, you have ...
A = 2((5.6 in)·(4.3 in) + (10 in)·(5.6 in + 4.3 in))
= 2(24.08 in² + 99 in²)
= 246.16 in²
x² + 8x + 8 = 0
x² + 8x + 8 + 8 = 0 + 8
x² + 8x + 16 = 8
x² + 4x + 4x + 16 = 8
x(x) + x(4) + 4(x) + 4(4) = 8
x(x + 4) + 4(x + 4) = 8
(x + 4)(x + 4) = 8
(x + 4)² = 8
