Answer:
Remove all perfect squares from inside the square root. ... I think it's about eighth or ninth grade. ... so if you have the cube root of the square root of (x-5) =2, you get ((x-5)^(1/2))^1/3 = 2, power to power requires multiplication, so (x-5)^1/6 = 2, ...

The answer is C
(x-h)^2 + (y -k)^2 =r^2
Center (h,k) r = radius
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
Answer:
c= -2.5-0.5d
Step-by-step explanation:
15=-3(2c+d)
15=-6c+-3d
15+3d=-6c
-2.5-0.5d=c
