$=(a^2-10a)-(b^2+6b) +16$
$=[(a^2-2(5)a+25)-25]-[(b^2+2(3)b+9)-9]+16$
$=(a-5)^2-25-(b+3)^2+9+16$
$=(a-5)^2-(b+3)^2$
5 x 4= 20
8 x 2 = 16
36 + 2 + 2 = 40
40 square inches

Answer:
There are 72 fligs in 12 flugs
Answer:
x ≈ 14.5
Step-by-step explanation:
A = x²√(25+10√5)/4
A = 1.72a²
x² = A/1.72
= 363.27/1.72
≈ 211
x = √211
≈ 14.5
