I believe that this would be (-3)²+-3. A negative times a negative is always positive, so -3² would be 9-3. We don't need the + sign because we would still subtract three from 9, which gives you 6. The answer would be C.

-3 squared is 9. 9 + (-3) is 6.

Therefore, it's C

Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation

Mariana [72]

Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.
