Answer:
Yes
Step-by-step explanation:
X2+10x+25=0
So let's solve
10=5,5
25=5,5
So let's continue
X2+5x+5x+25
Let's factorise
X(x+5)+5(x+5)=0
(X+5)(x+5)=0
So
X+5=0
Substrate 5 from both sides
X=-5(twice)
So the answer is yes
Answer:
x = -1 or 2
Step-by-step explanation:
Taking the antilog, you have the quadratic ...
x^2 -x -1 = 1
x^2 -x -2 = 0 . . . . subtract 1
(x -2)(x +1) = 0 . . . factor
The values of x that make these factors zero are the solutions to the equation.
x = 2 or x = -1
Given data:
The given distance Jadwiga runs in a day is 875 m.
The expression for the given statement is,
1d=875 m
Multiply the above expression by 7 on both sides.
7(1 day)=7(875 m)
=6,125 m
=6.125 km
Thus, Jadwiga covered 6.125 km in 7 days.
