It is the bottom Because If you addd it that’s what it would
A+b=-10
ab=-75
a=-75/b
-75/b + b = -10
-75/b + b²/b = -10b/b
b²+10b-75=0
(b+15)(b-5)=0
b+15=0 or b-5=0,
b= -15, a=5
6.5 meters is the answer, i know because i answered the same question on a quiz, i just guessed so i don't really have an explanation on why.
Answer: 1/3(12+x)
Step-by-step explanation:
One third the sum of 12 and a number can be written as 1/3(12+x). This equation can also be simplified to 4 + x/3, but sense the question doesn't ask you to do so, the answer most likely is 1/3(12+x).
