Answer:
the cubes are 1 in on all sides
but...
since there's gaps its more likely that there a 1/2 in or 3/4 in
Step-by-step explanation:
12/12=1
(X+3)^2+(y-2)^2= 16
The formula is (x-h)^2+(y-k)^2=r^2
Answer:
x² + 4x + 20 = 12x - 5
x² + 4x - 12x + 20 + 5 = 0
x² - 8x + 25 = 0
Δ = √b² - 4ac
= √(-8)² - 4×1×25
= √64-100
= √(-36)
x ∉ R
<u>Understanding:</u>
This can be easily solved by using the distance formula which is

distance
coordinates of the first point, in our case it is 
coordinates of the second point, 
<u>Solution:</u>

<u></u>
The distance between the two points is 5.
