I'm going to rewrite the equation assuming this is the correct form:
Answer:
x= -(d-a)/(b+c)
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero
Answer:
The value of x is
.
Step-by-step explanation:
It is given that the inverse variation equation is
..... (1)
The value of y is 4 and the value of k is 7.
Substitute y=4 and k=7 in equation (1).

Divide both sides by 4.


Therefore the value of x is
.
Answer:The Perimeter of Green Island is 1.6 km.
We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=27648
r=√[27648/(4*3)]-------> r=√2304-----> r=48 units
volume of a sphere=(4/3)*pi*r³-----> (4/3)*3*48³---> 442638 units³
the answer is
