Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!

Is 12n2+12n+1 prime over the set of polynomials with rational coefficients? Need help ASAP

professor190 [17]

Answer:

No, the given polynomial is not prime.

Step-by-step explanation:

Given: a polynomial $12n^2+12n+1$

To check: whether the given polynomial is prime or not.

Solution:

A prime polynomial is a polynomial that cannot be factored into polynomials of lower degree and has integers as coefficients.

In the given polynomial, coefficients are integers.

Also, the polynomial $12n^2+12n+1$ cannot be factored further into polynomials of lower degree.

So, the given polynomial is not prime.

On a coordinate plane, what is the difference between (-2,7) and (-2,-6)?

Shtirlitz [24]

If you mean distance, then we can use the distance formula to find out.

(x - x)² + (y - y)² = d² Distance formula
(-2 + 2)² + (7 + 6)² = d² Substitute the points; remember that when you subtract a negative, you add, and also remember to always subtract in the same direction (with the points (1,2) and (3,4), if you do 1 - 3, then do 2 - 4 and not 4 - 2)
(0)² + (13)² = d² Add
0 + 169 = d² Square
169 = d² Add
13 = d Take the square root of both sides to cancel out the exponent

The distance between (-2,7) and (-2,-6) is 13 units.

Hope this helps!

Which one doesn’t belong with the other three? Explain your reasoning plz plz answer #3

Ahat [919]

The box provides some examples of how exponents can be used to shorten repeated multiplication. The first, third, and fourth boxes all show how the repeated multiplication of 2, 3, and 5 can all be abbreviated as $2^4, 3^2$ and $5^3$ . The only expression which doesn't belong is $3+3+3+3=3(4)$ , because it's showing how repeated addition can be shortened to multiplication.
