Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
Answer:
c) (8^6) / 8 = 32768
d) (7^8) / (7^6) = 49

Hi there! The answer is 10.

We can use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Since we cannot work inside the parenthesis in this question and since we don't have exponents, we can move on to multiplying.

Our next step would be subtracting. To make the process of subtracting some easier, I'll first change the fraction into a decimal.

Finally subtract.

The answer is 10.

Answer:
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)
Step-by-step explanation:
<u>Part a:</u>
Given
Salary = $2500
Percentage of raise = 10%
The new salary will be:

<u>Part b:</u>
Given
Total questions = 40
Percentage of correct answers = 85%
The required expression for correct answers is:

<u>Part c:</u>
Given
Price of phone = $250
Percentage of sales tax = 7.5%
The required expression is:

Hence,
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)
