Step-by-step explanation:
You are doing simple math within the square root. For instance where x=-2 you substitute -2 for x then add 2 which gives you 0 leaving you with -6.
for x=2 you end up with "square root 2+2" which gives you 4 and the square root of 4 is 2 so you add -6 to 2 giving you the answer of -4.
G=gum
c=candy
2g+3c=3.25 4g+c=2.75
c=2.75-4g
2g+3(2.75-4g)=3.25
2g+8.25-12g=3.25
-10g=5.00
g=0.50 c=2.75-4(.50)
c= 2.75-2.00
c=0.75
If you are using a calculator, simply enter 78÷260×100 which will give you 30 as the answer.
