Answer:
d = 9
Step-by-step explanation:
Calculate the slope m of line AB and equate the result to 3
m =
with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(d, 21)
m = =
= 3 ( multiply both sides by d - 4 )
15 = 3(d - 4), that is
15 = 3d - 12 ( add 12 to both sides )
27 = 3d ( divide both sides by 3 )
9 = d
<h3>Answer: Choice C is correct</h3>
Explanation:
We can think of the square in the middle of the four others as the floor

The square at the very right side will then form the ceiling.
Side E and side L join at the top left edge.
