Answer:
I'm too tired to explain, here's some digital work on a site called Symbolab:
Answer:
(cx)2-(dy) 2
Step-by-step explanation:
Formula a2-b2= (a+b) (a-b)
By given formula
(cx)2 - (dy) 2 = (cx+dy) (cx-dy)
Answer: 37
Step-by-step explanation:
1) 38cm
2) 2304cm^2
3) 64cm^2
To find the area you multiply the sides
To find the perimeter you add the sides
You can round each number to the nearest half
12 3/8 = 12 1/2
6 7/8 = 7
Now, you have: 12 ½ × 7
Since you have a mixed number, change it to a decimal to make it easier.
12 ½ = 12.5
12.5 × 7 = 87.5
The product of 12 3/8 and 6 7/8 is about 87 1/2 = 87.5
