-
using properties of proportion find the value of x : x⁴+1:2x⁴::313:25
-
b is the main proportion between a and b prove a2-b2+C2/a-2-b-2+c-2=b4
- If y (3x- y) : x (4x+y) =5:12, find (x²+y²) : (x+y) ²
- what is the ratio and propotion
-
what number should be added to each of these
-
can you please explain this sum?
- If (7a+8b) (7c-8d) = (7a-8b) (7c+8d); then prove that a:b = c:d
-
