3x2 - 2
x + 4
The value of the 1st and 2nd expressions are 10 and 6 respectively.
A mathematical expression made up of integer constants, variables, and algebraic operations is known as an algebraic expression.
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.

The derivative is just the slope. So it's constant negative for the line up to x=-3. Then we have a parabola that will go linearly from a positive slope to zero at the origin to a negative slope at x=3. Then a constant positive slope.
So we're looking for flat negative line up to x=-3, linear starting positive and through the origin ending negative at x=3, then a flat positive.
Answer: third choice
Answer:
49 kg.
Step-by-step explanation:
We have been given that Ava's dog weighs 56 kilograms. Marty's dog weighs 7/8 as much. We are asked to find the weight of Marty's dog.
To find the weight of Marty's dog, we will multiply 56 by .
Therefore, the weight of Marty's dog is 49 kilograms.
In the number 6333, rounding to the place of the underlined digit (6) results in the number 6000, as the digit next to the 6 is less than 5.
In the number 6333, when we are asked to round to the place of the underlined digit - in this case, the 6 - we need to look at the next digit to the right, which is 3.
Since this digit is less than 5, when we round to the thousands place (the place of the 6), it remains the same, leading our rounded number to be 6000.
Remember rounding rules: 5 or more, we round up, and less than 5 we round down.
