The answer is quadratic.
A quadratic equation takes this form:
<em>ax^2+ bx + c</em>
The "a,""b,"and "c" represent numerical coefficients.
This is how your equation looks:
3x + x^2 + 4
Now it is standard that we organize the polynomial in descending order so it will look like this:
x^ 2 + 3x + 4
(commutative property of addition says that the arrangement will not affect the result)
It matches the quadratic polynomial form.
<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>
Answer:
WAIT A MINUTE MR. POSTMAN
Step-by-step explanation:
To solve this, you must find a common denominator (the number on the bottom of the fraction) before adding the numbers. The easiest was to do this is multiply the denominators together to get a common product. You then multiply by that number over itself, because that is equivalent to 1. So in this problem, you would multiply 3/4 by 19/19 and 18/19 by 4/4. Once you do this, you can add the fractions together.
The surface area of a regular tetrahedron is computed as the product of √3 and the square of the length of one side. The length given is 5 meters, by evaluating, we will have A = √3 (a²) = √3 (25) = 43.30. The answer is B.
Answer:
8. 11v
9. -19x
10. 6p
11. 16n
12. -4n - 5
13. 15r
14. 9n + 1
Step-by-step explanation:
8. -v + 12v = 11v
9. -8x - 11x = -19x
10. 4p + 2p = 6p
11. 5n + 11n = 16n
12. n + 4 - 9 - 5n = n - 5n + 4 - 9 = -4n - 5
13. 12r + 5 + 3r - 5 = 12r + 3r + 5 - 5 = 15r
14. -5 + 9n + 6 = 9n + 1
