Answer:
1. No
2. No
3. No
4. Yes
Step-by-step explanation:
Plug each option into u then solve the equation and see if the answer matches -15.
Ex. -15 = 1 -4 (2)
-15 = 1 -8
-15 = -7
-15 does not equal -7 therefore it is false. Use Pemdas to solve.
A mixed number is a number that has a whole number, and a fraction, so the mixed number that is equal to 7.6 is 7 6/10, simplified it would be 7 3/5
The first one is 11 and -11 because when you square them they both get 121
The second one is -7 and -1
