Answer:
2b^2
Step-by-step explanation:
according to the question equation is
(a^2 + b^2 ) - (a^2 - b^2)
a^2 + b^2 - a^2 + b^2
plus a square and minus a square gets cancel
b^2 + b^2
since they are like terms they can be added
2b^2
Answer:
Step-by-step explanation:
Minnesota: 86900 square miles
Wisconsin: 65000 square miles.
Net form

Minnesota is 1.33 times as large as Wisconsin.
Scientific notation
1.33 * 10^0
Minnesota is still 1.33 times as large as Wisconsin
The answer is 3140

Answer: 70$
Step-by-step explanation: Hope this helps <3
3x+4y = 375
6x+ 4y= 600
-------------------
6x-3x = 600 - 375
3x=225
x=225:3
x=75 cents
3*x+4y= 375
3*75+4y=375
225 +4y = 375
4y=375-225
4y=150
y=150:4
y=37,5 cents
the price is 75+37,5=112,5 cents for one bag of potato chips and one candy bar
