Answer:
The answer to your question is: the first option in the second line.
Step-by-step explanation:
- The first option to the left is incorrect because "-3" do not multiply all the function.
- The second option in the first line is correct to the fourth step, the next steps are not necessary.
- The first option in the second line is correct it shows all the necessary steps to evaluate the function.
- The second option in the second line is incorrect because it adds (-3 and -5) and it is wrong, first we must do multiplications and after additions and substrations.
Answer:
12
Step-by-step explanation:
So we use PEMDAS:
-5 + 8 = 3
3 + 9 = 12
Expressions are mathematical statements represented with the variables
The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
<h3>How to determine the value of the variable</h3>
The expression is given as:
When x = -1, the expression becomes
Evaluate the exponent
When y = 5, the expression becomes
Evaluate the exponent
- 12/5
Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

Answer:
The square root of 49 is 7.
Step-by-step explanation:
To find the square root of 49, you would need to look at the possible multiplication equations. For example:
1 x 49 = 49
7 x 7 = 49
49 x 1 = 49
As you can see, 7 x 7 would have the square root of 49, which is 7.
7^2=49
.
In conclusion, the square root of 49 is 7
The variable 'T' equals -20.
