b= 63 and that is your answer
Answer:
a square backyard with width (x - 9)
Step-by-step explanation:
x²−18x + 81 = x² - (2 x 9) x + 9² = (x - 9)²
width = area / length = (x - 9)² / (x - 9) = x - 9
Length = width
This is a square backyard
Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.
Answer:
300
Step-by-step explanation:
The total number of ratio units in 6:5 is 6+5=11, so each of those ratio units must stand for 550/11 = 50 detectives. Then the 6 ratio units of police detectives stand for 6·50 = 300 police detectives.
y = -8
y = mx + b, where m is the slope and b is the y intercept
since m = 0, the term mx = 0
since the line passes throug (7, -8) then y = -8
