Answer:
(The solved portion if needed)
Step-by-step explanation:
Let us break down each portion of the phrase: The sum of twice a number and 9 is -25.
The first important part is "The sum". This means that the next two listed numbers (Or expressions) will be added together
Next is, "A number and 9". "A Number" is just an unknown variable. We can just name this x. "And 9" shows the other number that is being added.
At this point we have
The next is, "is -25". Is means equals, so this part would be
Now we can put these two parts together to get

Answer:
103
Step-by-step explanation:
We substitute x with 5:
Solve the exponent first:
<em>Note: We are using order of operations (consecutively)</em>
- <em>Parentheses </em>
- <em>Exponents</em>
- <em>Multiplication</em>
- <em>Division</em>
- <em>Addition </em>
- <em>Subtraction</em>
Multiply:
25 * 4 = 100
Add:
100 + 3 = 103
Our answer is 103
