Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²
Area of Trapezoid = area of rectangle + 2(area of triangle)
= 28 + 2(10.5)
= 28 + 21 = 49
In short, Your Answer would be 49 cm²

Answer:
(x - 2)² - 30
Step-by-step explanation:
To complete the square

f(x) = x² + 2(- 2)x + 4 - 4 - 26 = (x - 2)² - 30
The best definition for the term substitution would be...
the action of replacing someone or something with another person or thing.
