Answer:

see explanation

Step-by-step explanation:

Evaluate u for each value of n by substituting value of n into u, that is

n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9

n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0

n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1

n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12

Thus

   n          u

   - 1         - 9

     0          0

      1          - 1

      2          - 12

How do you do this?
ELEN [110]
Use the Pythagorean Theorem: a² + b² = c².

a and b are the legs of the right triangle, and c is the hypotenuse.

2) 5² + b² = 6²
    25 + b² = 36
    b² = 11
    b = 3.3 cm

3) 7² + b² = 8²
    49 + b² = 64
    b² = 15
    b = 3.9 cm

4) a² + 5² = 13²
     a² + 25 = 169
     a² = 144
     a = 12 cm

What is the greatest perfect square that is a factor of 396? Explain
DedPeter [7]
<span>To find the greatest perfect square  that is a factor of 396, first we check what are the factors of 396
Factors of 396 are: 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396
Now we check which is the greatest perfect square in these. 
396, 198, 132, 99, 66,44 are not perfect square,
so 36 is the largest perfect square from the factors of 396, 6 x 6 = 6</span>² = 36
