Answer:
Associative property of addition. Grouping different addends does not change the sum.
Step-by-step explanation:
5 + 2 + 3 = 5 + (2 + 3)
10 = 5 + (5)
10 = 10
6561^1/2 (^1/2 means to the power of a half, which is the same as the square root)
9^2
3^4
2l + 2w = 16
2(l+ w) = 16 Divide both sides by 2
l + w = 16/2
l + w = 8
So for example the length l could be 5 and the width could be 3.
Length could be 5.
No, the tangent line needs to be against the circle from where it leaves. This is just a straight up right angle.
