15 Boys because 35-5 is 30 then divide 30 by 2 to get 15
Answer:
1/3
Step-by-step explanation:
(1/3)^2x(1/3)^-1
so, we can write this as:
1/3 x 1/3 x 3/1
if calculated by cutting, the answer is 1/3
There is also an easier way to do this,
(1/3)^2 x (1/3)^-1
as the bases are same, the powers will be added.
2+(-1)
2-1
=1
so,
(1/3)^1 or 1/3
X² + 11x - 26 = 0
x² - 25 = 0
(x + 13)(x - 2) = 0
(x + 5)(x - 5) = 0
x = -13
x = 2
x = -5
x = 5
