Answer:
4
Step-by-step explanation:
Let the number = x
Added to 11 = 11+x
Multiply result by 3 = 3(11+x)
Final result = 45
Solving
3(11 + x) =45
33 +3x = 45
3x= 45-33
3x=12
X=4 by dividing both side by 3
X² - 16xy + 64y²
= x² - 2*8xy + (8y)²
= (x - 8y)²
Answer:
side length = 0.8 yards
area = side length^2= 0.8^2 = 0.64 or 64/100
