Can someone help me with part A on this question? I'm stuck on it :(

Discriminant: b² - 4ac < 0

The equation has no real solution; two imaginary solutions.

Step-by-step explanation:

The discriminant, b² - 4ac is the expression under the radical of the quadratic formula, .  Knowing the value of a quadratic equation's discriminant allows us to determine its nature (real or complex) and its number of solutions, if any.  

The following values of discriminant define the nature and number of solutions:

b² - 4ac = 0 ⇒ The equation has one real solution or root. This means that the graph will cross the x-axis once.

b² - 4ac > 0 ⇒ The equation has two real solutions or roots. This means that the graph will  cross the x-axis twice.

b² - 4ac < 0 ⇒ The equation has no real solution or have two imaginary roots.  This means that the graph will not cross the x-axis at all.

Provided these definitions, it is easier to determine the possible discriminant for your given graph: b² - 4ac < 0 since the parabola doesn't cross the x-axis at all. This implies that the quadratic equation doesn't have any x-intercepts.

Therefore, the given graph of a quadratic equation does not have any real solution (no solution). Instead, it will have two imaginary or complex solutions or roots.  

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
