Used half, half left
10 of cat
14 left
so
half=left=10+14=24
so whole = double the half or 2 times 24=48
answer si 48 exposures
Answer:
Step-by-step explanation:
x + y + z = 180
w + z = 180
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w(
The perimeter means you add up all the sides
so you do
(12b-8) + (12b-8) + (9b+8)
now you just add the like terms
12b+12b+9b = 33b
-8+-8+8= -8
so the perimeter is 33b-8
