-2
0
3

Answer 1
Answer:

Answer:

The possible value of 'x' is: 3.

Step-by-step explanation:

A polynomial has no real solutions when the discriminat is less than zero. Given the following polynomial: ax^(2) +bx+c = 0 the discriminant is given by: Discriminant = b^(2)-4ac

In this case, a=1, b=2. By substituting those values:

Discriminant = 2^(2)-4(1)c ⇒ Discriminant = 4-4c

Given that the discriminant should be less tha zero, then 'c' must be greater than one.

In this case, the only possible value of 'x' is: 3.
Answer 2
Answer:

Answer:

3

Step-by-step explanation:

Given

x² + 2x + c = 0 ← in standard form

with a = 1, b = 2 and c = c

If there are no real solutions then the discriminant

b² - 4ac < 0, that is

2² - (4 × 1 × c ) < 0

4 - 4c < 0 ( subtract 4 from both sides )

- 4c < - 4

Divide both sides by - 4, reversing the sign as a consequence

c > 1

Hence a possible value of c is 3

How to write 13/4 as a mixed number

Answers

13/4
3 1/3

Answer: 3 1/3
It's 3 and 1/4.You work out how many times the denominator goes into the top. In this case it's 3 and thus becomes the big number. The remainder is 1 which is written over the original denominator which would be 1/4.

HELP ME PLEASE I BEG YOU!!!!!!!!!!!!!

Answers

the answer to this are:
1) D
2) A and B
3) C

hope this works.

3.) r=2: 2+4/15= 6/15=2/5

2.) -3a-15=a: the fraction is negative. meaning the answer is negative, leaving a and c as choices. You can't square a since it is on different sides of the equation leaving you with c.

1.) answer is 5(x+4)=30: 3 is 2, meaning you would use the 2.
