If the area was 16cm^2 before, then each side was 4 cm long since each side of a square is equal, and the area for a square is the length of the sides squared. The square root of 16 is 4, so that is why the sides were 4 cm. When you make each side 1 cm shorter, they're now all 3 cm. 3^2 is 9, so the new area is 9 square centimeters.
A(n) is a special type of hyphen that prevents two words separated by a hyphen from splitting at the end of a line.

Subtract
7 2/4 - 5 1/4
2 1/4
Answer:
a=25,b=-23
Step-by-step explanation:
f(x)=6x-5
a. f(5)=6(5)-5
f(5)=30-5
f(5)=25
b. f(-3)=6(-3)-5
f(-3)= -18-5
f(-3)=-(18+5)
f(-3)=-(23)
f(-3)=-23
