Let the actual size be x, then
(5 x 10^2)x = 1.2 x 10^2
x = (1.2 x 10^2 / 5 x 10^2) = 0.24 millimeters
Therefore, the actual size is 0.24 millimiters.
5≥|4-2x|
5≥4-2x≥-5
-1≤2x≤9
-0.5≤x≤4.5
x∈[-0.5;4.5]
Sophia’s work factoring a perfect square trinomial is 
Step-by-step explanation:
We have,
16
– 40x + 25
=
- 2(4x)(5) + 
Using the algebraic identity,

=
- 2(4x)(5) + 
≠ (
Thus, Sophia’s work factoring a perfect square trinomial is
