Answer:219.96 yd²
Explanation:The area of the trapezoid can be calculated using the following rule:Area of trapezoid =

where:
b1 is the length of the first base
b2 is the length of the second base
h is the height
Now, in the given we have:b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd
Substitute with the givens in the above equation to get the area as follows:area =

A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
Answer:
A.
(x - 3)(x - 3)
Step-by-step explanation:
x^2 – 6x + 9
What 2 numbers multiply to 9 and add to -6
-3*-3 =9
-3+-3 = -6
(x-3) (x-3)
