Distance hiked by Sara last week = 8 miles
Distance hiked by Sara on Monday this week = 3 miles
<span>Distance hiked by Sara on Tuesday this week = 4 miles
</span><span>Distance hiked by Sara on Thursday this week = 3 miles
</span>So
Total distance hiked by Sara this week = (3 + 4 + 3) miles
= 10 miles
The number of more miles hiked by Sara this week = (10 - 8) miles
= 2 miles
Answer:
The quadratic equation is x^2-2x-4
Step-by-step explanation:
We want to know the equation that has the solution below;
x = 1 ± √5
This means x = 1 + √5 or 1 - √5
The equation would thus be;
(x-1-√5)(x-1+ √5)
= x(x-1+ √5)-1(x-1+ √5)-√5(x-1+ √5)
Opening the brackets we have ;
x^2-x+ √5x-x + 1 -√5-√5x+ √5-5
collecting like terms we have;
x^2-2x+1-5
= x^2-2x-4
