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

-1. Plug in -3 for x which makes 9-10 so -1
Answer:
x=12
Step-by-step explanation:
tangent forms 90° with the touch point at circle
(x+8)^2 = 256+x^2
x^2 + 16x + 64 = 256 + x^2
16x = 192
x= 12
Answer:
1,350 cm^2
Step-by-step explanation:
It's a cube so all faces/bases are the same.
15 × 15 = 225
225 × 6 = 1,350
The rules of exponents tell you that you can distribute the exponent to each of the factors. When one already has an exponent, those exponents multiply.
