Answer:
269
Step-by-step explanation:
6(3)+23+(7)(33)-3
\/ \/
18 + 23 + 231 - 3 = 269
The ar. of square =X^
=5.76
So,X=√5.76
=2.4
now, perimeter of square =4(X)
=4(2.4)
=9.6
So, the perimeter of the square is 9.6cm..
Thanks!
Hope it helps you..
It is in the thousandths place.
I am unsure about the very last problem but I can help with the first two
1) (y+1)+4
If we combine the numbers 1 and 4, we get +5 and can isolate the numbers from the variable.
This would give us
![y + 5 =](https://tex.z-dn.net/?f=y%20%2B%205%20%3D)
2) (6*r)*7
remember that we do not have to explicitly state 6*r
Instead, we can write it as 6r
this helps us get rid of the parentheses
now we can write it as
![6r * 7=](https://tex.z-dn.net/?f=6r%20%2A%207%3D)
I hope this helps!:)
