Answer:
1: A) 12 meters
2: B) 225 = (12 + x)(14 + x)
Step-by-step explanation:
42 times 2 = 84
84/12 = 7
(To check) 12 - 7 = 5
I'll be expecting that brainliest :)
2. b=-15 4. b=9 5. m=6 b=1 6. m=-4 b=140
x = 3 is a vertical line that goes straight up and down at 3 on the x axis, vertical lines have a undefined slope. Don't confuse that with no slope which is a flat like like y=7.
so the slope is undefined
S=i(n-1)+2*(n-1)+1 perhaps
