Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
Answer:

Step-by-step explanation:
Degree is the highest exponent on the variable in a polynomial.
A leading coefficient is the first terms coefficient when the polynomial is written in standard form.
To write this polynomial, write
as your first term. Its leading coefficient is -4 and it has a degree of 3. Then add whatever terms after it being sure to not add any more with exponent 3 or higher.
Example: 
The values of y are 7, 8.5, 10.5 and 11
<h3>How to determine the values of y?</h3>
The equation is given as:
y = 1/2x + 5
The domain is given as:
Domain = 4, 7, 11, 12
This means that
x = 4, 7, 11, 12
Substitute x = 4, 7, 11, 12 in the equation y = 1/2x + 5
So, we have:
y = 1/2 * 4 + 5 = 7
y = 1/2 * 7 + 5 = 8.5
y = 1/2 * 11 + 5 = 10.5
y = 1/2 * 12 + 5 = 11
Hence, the values of y are 7, 8.5, 10.5 and 11
