B.). 3/2 x+2
D.). 19x+9y
F.). 2x+3y+7
H.). Could not understand at the end
Answer:
1.) 22+(33+44)
2.) (5+3)+(1+9)
3.) (-a+d)+(-c+b)
Step-by-step explanation:
Associative property of addition: Changing the grouping of addends does not change the sum. For example,
(2+3)+4= 2+(3+4)
No matter how you rearrange the numbers, they will always add to the same amount.
Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square:
, where s = side
, where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
. Area of square is 16
. Area of trapezoid is 12.- 16 + 12 = 28
Therefore, the area of the figure is 28 units^2.
