Step-by-step explanation:
x²-11x+32=4
x²-11x+28=0
(x-4)(x-7)=0
x=4 or x=7
_______
x²+8x-5=4
x²+8x-9=0
(x+9)(x-1)=0
x=-9 or x=1
_______
x²+x+4=5x+1
x²-4x+3=0
(x-1)(x-3)=0
x=1 or x=3
________
x²+x-24=-8x-2
x²+9x-22=0
(x+11)(x-2)=0
x=-11 or x=2
X + 2 = 3/5(10) - 3
x + 2 = 6 - 3
x + 2 = 3
x = 3 - 2
x = 1 <=== ur number
Given:
The equation is

To find:
The value of x.
Solution:
We have,

Isolating the variable, we get




Therefore, the value of x is 44.2.
1 kilometer = 1000 meters so 12 kilometers = 12000 meters
10 laps (400 meters/lap) = 4000 meters
12000/4000 = 3
Answer: 3 days
It would be associative property because the order of the numbers stayed the same
