The polynomial that represent twice the sum of 
- x +6 and 7
+ x -1 is : 4+10
<h3>What is a polynomial?</h3>
A polynomial is any algebraic expression that has the least value of the power of its variable as 2.
When the highest value of the polynomial is 2, it is a called a quadratic expression.
Analysis:
2( -5 -x +6 + 7 +x -1)
2( 2 + 5) =
4 + 10
In conclusion, the polynomial that represents the above expressions is 4 + 10

<h3> Answer:</h3><h3>The simplest form of 477/636 is 3/4.</h3><h3>The simplest form of 361/418 is 19/22</h3>
Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:
From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:
The significance level is 0.01, so the critical value tc should be the one that satisfies:
Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
Answer:
No

The Side-Angle-Side rule of congruence
two triangles are congruent if two sides and one included angle in a given triangle are equal to the corresponding two sides and one included angle in another triangle.
