Answer:
87.48
Step-by-step explanation:
First find the area of the square
12^2=144
find area of the 2 circles
9*3.14
but theres 2
18*3.14=56.52
144-56.52=87.48
D is the correct answer luv
Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!
It would be 100 because they are vertical angles
Answer:
a=b
Step-by-step explanation:
An antisymmetric relation () satisfies the following property:
If (a, b) is in R and (b, a) is in R, then a = b.
This means that if a|b and b|a then a = b
If a|b then, b can be written as b = an for an integer n
If b|a then a can be written as a= bm for an integer m
Now we have b = (a)n = (bm)n
b = bmn
1 =mn
But since m and n are integers, the only two integers that satisfy this property would be m = n = 1
Therefore, b = an = a (1) = a ⇒b = a
