Step-by-step explanation:
calculate the area of the shape(s) on the inside and then the area of the sphape on the outside, then subtract the inside's area from the outside shape. im still working on this one, check back in a bit.
I say the 6 and the 9 because you see it through out a lot and u add and subtract 3 you get the same answer.
So first we were to told that the sum of 2 numbers add to 19
a+b=19---------(1)
and they subtract to 5
a-b=5-----------(2)
These are two simultaneous equation and can be solved by elimination:
(1) + (2):
(a+b)+(a-b)=19+5
2a=24
a=12
12+b=19
b=7
So the two numbers are 12 and 7
