c + 2c = 33
3c=33 (now divide by 3 both sides of equation)
c=11
so Ann has 11 apples (c=11) and her brother has 22 apples (2c=2×11=22)
They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1
& so on & so forth

ans=1
Step-by-step explanation:
I think the ans is =1
A²+b²=c² according to pythogoras theorem.
a²=11.31²-8²
a²=127.91 - 64
=63.91
a=√63.91=7.99 = aprox. 8
Answer:
B -2x - 12y
Step-by-step explanation:
-8x + 6x = -2x
12y - 24y = -12y
-2x - 12y
