Answer is 210/39.37 metres because you divide by number of inches to get metres
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)
<em>n = 4</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>²⁾2n + n/2 = ²⁾10</em>
<em>4n + n = 20</em>
<em>5n = 20</em>
<em>n = 20 : 5</em>
<em>n = 4</em>
<em>Good luck !</em>
Answer:
{1}
Step-by-step explanation:
We find determinant for the given matrix and set it equal to -1
To find determinant we apply formula
|A| = x^2 - 2x
Now we set the determinant = -1
Add 1 on both sides
Now factor it
(x-1)(x-1) = 0
Set each factor =0 and solve for x
x- 1=0 so x=1
