Counting all of the lines, there is About 17
Answer:
Step-by-step explanation:
The zeros are the values of x for which y = 0
Quadratic formula
x = [5 ± √(5² – 4·1·6)] / [2·1]
= [5 ± √1] / 2
= [5 ± 1] /2
= 2, 3
sum of zeros = 5
Answer:
−20.25
Step-by-step explanation:
First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is
4(x+8)(x-2)
Answer:
x=4
Step-by-step explanation:
ABCD is a rectangle, so AD and BC are parallel. Thus, The angle complementary to 6x+19 is 47.
6x+19+47=90
6x+66=90
6x=24
x=4
