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.
Answer:
width is 4 meters
Step-by-step explanation:
A = l*w where l is length and w is width
28 = 7*w
Divide each side by 7
28/7 = 7w/7
4 =w
Answer:
1/2y > 22
Step-by-step explanation:
I think that's what you were asking, but I'm not sure
So the is more than tells you that you're going to use the greater than sign. and 1/2 of y is 1/2y because of means mulitiplication
hope this helps:)
