the distance from the origin is 5, so
sqrt(x²+y²)=5
x²+y²=25
substitue y=x²
y+y²=25
y²+y-25=0
solve using calculator or the formula
to get
y =( -1+sqrt(1+4*25))/2
or y = (-1-sqrt(1+4*25))/2
the second solution is rejected because a square cannot be negative
the value of x is the positive or negative (sqrt... or -sqrt...) or y

Step-by-step explanation:
The answer is: " h = A / b " .
_________________________________________________________
Explanation:
_________________________________________________________
Given: " A = bh " ; Solve for "h" ;
_________________________________________________________
A = bh ;
↔ bh = A ;
Divide each side of the equation by "b" ; to isolate "h" on one side of the equation; & to solve for "h" ;
→ (bh) / b = A / b ;
to get:
→ h = A / b .
_________________________________________________________
The answer is: " h = A / b " .
