Answer:this one
●________>
Step-by-step explanation:
Answer:
The answer is x= -1.9.
Use the 3 to multiply the number and the letter in the bracket... which is...
3x-24=-29.7.
3x=-29.7+24.
3x=-5.7.
x=-5.7/3.
x=-1.9.
The order of operations tells you exponentiation is done before multiplication or addition. That is, the value of x is squared before the sign is applied.
Your result will be negative for any non-zero value of x.
