2/3 and 0.667 are rational numbers equivalent to 6/9
For simple integer factors as this one has, you want to find two values for the quadratic in the form ax^2+bx+c. Let the two values be j and k. These two values must satisfy two conditions.
jk=ac=10 and j+k=b=11, so j and k must be 1 and 10.
Now replace bx with jx and kx...
2x^2+x+10x+5 now factor 1st and 2nd pair of terms.
x(2x+1)+5(2x+1)
(x+5)(2x+1)
Answer:
The distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Step-by-step explanation:
Given the points
Finding the distance between (-1, 1) and (2, -4) using the formula
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
units
or
units
Therefore, the distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Answer:
Step-by-step explanation:
There are many ways this could be done, but the simplest way is to divide 18 into 72. That gives 4. So each plot is 4 * 20 = 80 m^2
If you are willing to use fractions, the answer could be 20*72 / 18 = 8 * 10 which is more feasible and still gives 80, but the land may not permit it. However math will.
It's hard to give an exact answer when it is this open ended.
