I get w = 15. So Semir walked 15 miles and Sarah walked (2(15) - 5) miles, or 25 miles.
It is the last one have a great day!
Answer:
115
Step-by-step explanation:
(ab)² and ab² are not equal. When you have something in parentheses being squared, you have to square everything inside, so in the case of (ab)², you have to "distribute" the ² to both variables inside. That gives you a²b², not just ab².
If the abstract way is kind of confusing for you, just pick two random numbers for a and b and plug them in to test it. Say a = 3 and b = 4. Then
(3*4)² = 3*4²
(12)² = 3*16
144 ≠ 48
24/200 x 100/1= 12% that means 24 on 200 times a hundred on 1
