The sum of -4 and 3 complain more because its negative
Answer:
120cm^3
Step-by-step explanation:
Sarahtime (min) {3 } 5 12 17
distance (meters) {75} 125 300 425
Eva time (min) {2} 7 10 20
distance (meters) {52} 182 260 520
Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min
Eva :meters over min= 52 over 2 =26 over 1
26 meters per min
eva is the faster swimming because 26 meters per min is faster then 25 meters per min .
i hope this help
1. u must simplify 3^2 first because the order of operations states that u have to do exponents before subtraction.
2. 12 - 3^2 = 81......she subtracted the 3 first....12 - 3^2 = 9^2 = 81...which is an incorrect answer
3. u do not divide before simplifying 3^2.....order of operations states that u have to do exponents before division
4. no.....(12 - 3)^2 ......order of operations states that u do parenthesis before exponents...so (12 - 3)^2 = 9^2 = 81
