Answer:
6x - 24y
Step-by-step explanation:
First, eliminate the braces by doing the multiplications:
-30x - 12y + 36x - 12y
Then group together the same variables:
6x - 24y
arguably, you could factor out a 6 and get:
6(x-4y)
but it is a matter of taste if that is simpler...
Answer:

Step-by-step explanation:
The similar triangles are drawn in the figure attached.
As shown in the figure, the smaller triangle ΔABC, and the larger triangle ΔA'B'C' share the same slope; therefore, the slope of the hypotenuse is the length of the triangle ΔA'B'C' divided by its base:

Therefore, the equation of the hypotenuse is

Answer:
city block cleaned on Monday =4
on Tuesday
city blocked cleaned = 21/6*city block cleaned on Monday
= 21/6*4 = 14
Answer: 9.
