Answer:
9x^2 - 10x -4
Step-by-step explanation:
It is set up like this
9x^2 - 8x
- (x-2)2
First solve (x-2)2
the answer is (2x-4)
so now you can do this instead
9x^2 - 8x
- 2x - 4
----------------------------------
9x^2 - 10x +4
9x^2 minus zero is 9x^2
-8x-2x is -10x
0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive
A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus
like this
9x^2 - 8x
+ -2x + 4
----------------------------------
9x^2 - 10x +4
C=2πr r radius it would be right
A Prime Number can be divided evenly only by 1 or itself.
And it must be a whole number greater than 1.
1st, 9/14 = .643 and 8/21 = .381.
2nd, 9/14 x 8/21 = .643 x .381
3rd multiply and solve .643 x .381 =
4th answer is 0.245
