Answer:
2(2n² + 2n) + 1
Step-by-step explanation:
(2n + 1)² can also written as
(2n + 1) × (2n + 1)
= 4n² + 2n + 2n + 1
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
= an odd

The values of the x that satisfies the equation 2x² + 7x +3 = 0 is -1/2 and -3 .
<h3>What is a polynomial function?</h3>
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
2x² + 7x +3 = 0
2x² + 6x + x + 3 = 0
2x (x+3) + 1(x + 3) = 0
(2x + 1)(x + 3) = 0
2x+ 1 = 0 ; x + 3 = 0
x = -1 / 2 ; x = -3
Thus, the values of the x that satisfies the equation 2x² + 7x +3 = 0 is -1/2 and -3 .

Answer:
Greta spends$25-$20=$5per week.
To solve this problem, we have to use the interior angles theorem which states that the sum of all three interior angles of a triangle must sum 180°.
Having said that, we express the following.
Now, we solve for <em>x</em>.
Then, we use this value to find the angle T.
<h2>Therefore, the angle T is equal to 70°.</h2>
