Answer:
−24x2+12xy+6x
Step-by-step explanation:
6x(2y−4x+1)
=(6x)(2y+−4x+1)
=(6x)(2y)+(6x)(−4x)+(6x)(1)
=12xy−24x2+6x
Answer:

Answer:
235 cm²
Step-by-step explanation:
Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.
Length of big rectangle=20 cm
Width of big rectangle=9 cm
20x9=180 cm²
Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.
Length of small rectangle=11 cm
Width of small rectangle=5 cm
I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.
11x5=55 cm²
Add the areas of the two rectangles.
55+180=235 cm²
