Answer:

Step-by-step explanation:
<u>Area of trapezoid</u>
Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

The dulcimer has the following dimensions


and height h
Thus

Operating


Is the required polynomial
Answer:
d = 101
Step-by-step explanation:
t = 11
11 x 11 = 121
-20 + 121 = 101
check: 101- 121 = -20 (correct)
D) the x intercept as you let each bracket equal to 0 to find the x coordinate
