Answer:
the third one 10 cm, 9cm 9cm
Answer:
Step-by-step explanation:
Hello, as alpha and beta are zeroes of

it means that their sum is alpha+beta=1 and their product alpha*beta=-2.
The polynomial whose zeroes are 2 alpha + 1 and 2 beta + 1, means that the sum of its zeroes is 2(alpha+beta)+2=2+2=4
and the product is (2alpha+1)(2beta+1)=4 alpha*beta + 2(alpha+beta) + 1 = 4 * (-2) + 2*(1) +1 = -8 + 2 + 1 = -5. so one of these polynomials is

Thank you.
<em>The result is -13</em>

Explanation:</h2><h2 />
Here we have the following addition problem:

So let's solve this step by step:
Step 1. Perform two plus two.

So:

Step 2. Perform the subtraction.
Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:

<em>Finally, the result is -13</em>
