Answer:
x = 8.64
x = - 7.64
Both to 2 d.p
Step-by-step explanation:
Firstly, - 8 both side - cancels the +8 & get the surd to equal x - 8
Then, square root both side, to get:
x-2= x^2 - 64
+ 2 both side
x = x^2 - 66
-x
0= x^2 - 66 - x
x^2 - x - 66 = 0
general equation for quadratic is ax^2 + bx + c
Now, we can find the value of a, b, c using x^2 - x - 66 = 0
a=1
b= - 1
c= - 66
Now use quadratic formula
x = -b±√(b²-4ac))/(2a
= --1 + √ - 1 x - 1 - 4x1x-66 / 2x1
= 8.639.....
Now repeat with - b - & not - b +
x = -b±√(b²-4ac))/(2a
= --1 - √ - 1 x - 1 - 4x1x-66 / 2x1
= - 7.639.......
Answer:
The total distance he walked was 17/10 miles or 1.7 miles.
Step-by-step explanation:
Ron's walk was divided into two parts, one that goes from his grandmother's house to the store and then from the store to his house. The total distance that he walked is given by the sum of the two separate parts, so in order to calculate how far he walked we will do as follows:
Total distance = 8/10 + 9/10
Total distance = 17/10 mile = 1.7 miles
The total distance he walked was 17/10 miles or 1.7 miles.
