Answer:
(x-4) (x-2)
Step-by-step explanation:
x^2−6x+8
What 2 numbers multiply to 8 and add to -6
-4*-2 = -8
-4+-2 = -6
(x-4) (x-2)
Step-by-step explanation:
4x + 2y = 10 --------(1)
2x + 3y = 33 -----------(2)
Multiply 2 with eq. (1) and 4 with eq. (2)
8x + 4y = 20 ____________(3)
8x + 12y = 132 ______(4)
Subtracting (3) from (4),
8x + 4y = 20
- 8x -12y = -132
----------------------
0 -8y = -112
y = 112/8
y = 4 is the answer.
Putting the vakue of y in eq. (2),
2x + 12 = 33
2x = 33-12
2x = 21
x = 21/2 is the answer.
For Ms Hurst:
Distance covered by her = Speed * time taken by her
Given:
Speed of Ms Hurst = 10miles/min
Time taken = 60 mins (since they both ran for 60minutes)
Substitute into the formula
Distance covered by Ms Hurst = 10mil/min * 60min
Distance covered by Ms Hurst = 600 miles
Hence Ms Hurst completed 600 miles
