Answer:
9x^2(5y^2 + 2x).
Step-by-step explanation:
First find the Greatest Common Factor of the 2 terms.
GCF of 18 and 45 = 9
GCF of x^2 and x^3 = x^2.
The complete GCF is therefore 9x^2.
So, dividing each term by the GCF, we obtain:
9x^2(5y^2 + 2x).
252, 210 divided by 5 = 42, 42 x 5 = 210 + 42= 252
A is the mid point ==> AL = AB = 2AB
6x-17=2(2x+3) => 6x -17 = 4x +6 => 2x = 23 =>x=23/2
then just plug x into LB and AB
Answer: (10,9) is the correct answer.
Part A number of combinations of 8 from 10 = 10C8 = 10C2
= 10*9 / 2 = 45
Part B Number combinations = 10C4 = (10*9*8*7)/ (4*3*2) = 210
Total number of ways = 45 * 210 = 9450 (answer)
