Answer:
147 photos
Step-by-step explanation:
63 photos -> 9 minutes
To find the number of photos scanned per minute, divide both sides by 9.
photos -> 1 minute
To find 21 minutes, we can do 
All triangles have angles that add up to 180 so the first one add 76 and 59 and subtract that from 180 to get the missing angle remember EACH triangle is 180 degrees when ALL the angles are added together on the ones with x solve for x then figure out the answer from there hope this helps
The answer is the first one: (z+1)(y+6).
Explanation:
yz + 6 + y + 6z
= yz + y + 6 + 6z
= y(z+1) + 6(1+z)
= (z+1)(y+6)
For (z+1), you can also write (1+z), it doesn’t matter.
Hope it helps!
Answer: I know D it’s 18.6
The circumcenter is where the perpendicular bisectors meet.
if you sketch the triangle, you will see that it is a right triangle, with the right angle vertex at (2,1)
one perpendicular bisector is x=1, another perpendicular bisector is y=3
they meet at (1,3)
so (1,3) is the answer.
