Answer:
0, 1
Step-by-step explanation:
The discriminant is b² - 4ac where we have ax² + bx + c, in this case a = -4, b = 12, c = -9 so D = 12² - 4(-4)(-9) = 0.
Because the discriminant is 0 that means that f(x) only has one solution for x meaning that it has only 1 x-intercept.
For #1-6, I'll write down the spelling errors first, and the correct spelling in bold. #7 will have the incorrect sentence first, and the sentence with correct punctuation in italics, with the punctuation bold.
1. super sonic supersonic
2. sub marine submarine
3. sub way subway
4. super natural supernatural
5. out field outfield
6. super star superstar
7. Do you like sports. <em>Do you like </em><em /><em>sports</em><em>?</em><em />
<em /><em />For #8-16, the word in bold is the correct spelling.
8. submarine submareen submarein
9. subdivsion subdivison subdivision
10. subersonic supersonic supresonic
11. underline undeline undrline
12. outfeild outfeeld outfield

Answer:
First: 12 feet
Second: 11 feet
Third: 14 feet
Step-by-step explanation:
Let the second side of the traingle be x
First side of the triangle= x+1
Third side of the triangle= x+3
x+x+1+x+3 = 37
3x+4 = 37
3x = 37-4
3x = 33
x = 11
First side of the triangle= (11)+1
= 12
Second side of the triangle= 11
Third side of the triangle= (11)+3
= 14
