Answers
The value of the 1st and 2nd expressions are 10 and 6 respectively.
What is an algebraic expression?
A mathematical expression made up of integer constants, variables, and algebraic operations is known as an algebraic expression.
How to solve this problem?
We have to find the values of the given expressions 3x² - 2 and x + 4 at x = 2.
Put x = 2 in 3x² - 2 and x + 4 to get the desired results.
Now, 3x² - 2 = 3(2)² - 2 =3(4) - 2 = 12 - 2 = 10
and x + 4 = 2 + 4 = 6
Therefore, the value of the 1st and 2nd expressions are 10 and 6 respectively.

Answer:
16
Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.

tax (27,225 * 6%) 1,633.50
total 28,858.50
license & reg. fee 50.00
total cost 28,908.50 Choice D.
Answer:
D. $28908.5
Step-by-step explanation:
We have been given that Ray Cupple bought a basic car costing $26,500.00, with options costing $725.00.
So the cost of car after options costing will be: .
Since there is a 6% sales tax in his state , so the cost of car after sales tax will be $27,225 plus 6% of $27,225.
We are also told that there is a combined $50.00 license and registration fee, so the total cost of car will be $28,858.50 plus $50.
Therefore, the total cost of the car is $28908.50 and option D is the correct choice.
