Let's do this using the process of elimination. Since you didn't include choice D, we can only use A, B, and C.
C: If we're finding the width of the patio, how is the thickness of the tiles going to help? C is wrong.
A: We already know the area (72), so how does knowing the perimeter help us? All we know using that information is that 2 pairs of numbers give us the perimeter & also multiply to get 72. But not <em>which</em> 2. A is wrong.
B: Pay more attention to the last part of B... "the length". Well, if we have the area (72), and we have the length, then we can do area/length-width to find the width. B is correct!

Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
Step-by-step explanation:
1 and 7/8, subtract 4 and 3/8 by 2 and 1/2.
Answer:
<h2>The slope is 2</h2>
Step-by-step explanation:
Step one:
we are required to find the slope of the given data points
A(4,6) B(5,8)
hence the x and y values correspond to
x1=4
y1=6
x2=5
y2=8
Step two:
Required is the slope which is
slope= y2-y1/x2-x1
Slope=8-6/5-4
Slope= 2/1
<em><u>Hence the slope of the ordered pair is 2</u></em>
