16x^2−81
Not difference of squares:
20m^2n^2−121
p^8−q^5
Step-by-step explanation:
y^4−25
(y²)² - 5²
16x^2−81
(4x)² - 9²
20m^2n^2−121
20 is not a perfect square
p^8−q^5
q⁵ is not a perfect square
Let us subtract equation 1 from equation 2.
5x - 3y - 2x + 3y = 7 - 4
3x = 3
x = 1
Substituting this value of x in equation 1, we get
2x - 3y = 4
2 - 3y = 4
-3y = 2
y =

Answer:
B. multiplying the percentage of work done by the physical units.
Step-by-step explanation:

If the physical units are 100 percent complete, equivalent units will be the same as the physical units. However, if the physical units are not 100 percent complete, the equivalent units will be less than the physical units.
