Answer:
4,443,000,000 or 4.443 * 10^9 km.
Step-by-step explanation:
Neptune's distance from the sun = 4.5 * 10^9
= 4,500,000,000 km.
The required difference is
4,500,000,000 - 57,000,000
= 4,443,000,000 or 4.443 * 10^9.
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2
your question is
z²+1+y where, y=4,z=3
3²+1+4
9+5
14
is your answer
