Hi
I belive you add the top side (4) plus the bottom side (9.5) witch would equal 13.5 times the hieght (3) equals 40.5 divided by 2 equals 20.25. the area is 20.25ft squared
another way to do it
4+9.5= 13.5
13.5×3= 40.5
40.5÷2= 20.25ft
Answer:
y = 9

3 × 3 = y
2) Simplfiy 3 × 3 to 9.
9 = y
3) Switch sides.
9
Answer:
x = (a - 2w)/2
Step-by-step explanation:
a = 2x + 2w
a - 2w = 2x
(a - 2w)/2 = x
The length of rays has no effect upon the angle between them. You can extend rays infinitely and the angle between them remains constant.
Everyone works differently in mental math.
Using the property of commutativity, we can (mentally) rearrange to calculate 89+11 + 27
Since 89+11 is exactly 100, the sum is therefore 100+27=127.
