Answer:
2x + 3x - 2y + 4y +7
Step-by-step explanation:
2x and 3x added together is 5x
2y and 4y added togther is 6y
and i left 7 alone, but you could do something to it if you'd like to
27
9+8+10=27
height = 12 cm
Parallelogram 1:
Area = base *height = 20 * 15 = 300 sq. cm
Area of parallelogram 2 = area of parallelogram 1
25 * height = 300
height = 300/25
I'm doing the same thing and, I don't understand it either.
