Answer:
(3x -1) (3x+1)
Step-by-step explanation:
9x^2 - 1
Rewriting
(3x)^2 -1^2
This is the difference of squares a^2 -b^2 = (a+b) (a-b)
(3x -1) (3x+1)
Answer:
Step-by-step explanation:
Initial # = 176 fans
Final # = 202 fans
Increase = 202 - 176 = 26 fans
% increase = 100% x (Increase / initial #)
= 100 x (26/176)
= 100 x 0.1477
= 14.78%
Answer:
a) n (A) = 7
Step-by-step explanation:
Here, set A = {2,5,7,9,13, 25, 26)
Noe, for any set A,
n (A) is defined as he total number of elements in the set A.
or, n(A) = CARNALITY OF SET A
Here,the number of elements in set A = 7
⇒ n (A) = 7
The rule for clockwise rotation of 90 degrees about the origin is (-y, x).
So (-1,9) would now be (-9,1).
Hope this Helps!!
