Answer: D = -8

Step-by-step explanation:

Ohh okk so the discriminant basically helps find the number of solutions to a quadratic equation

If D(discriminant) is:

< 0 there are no solutions

= 0 there is one solution

> 0 there are two solutions

The discriminant is found using

b^2 - 4ac

Here a = 3

b = -4

c = 2

(-4)^2 - 4(3)(2)

16 - 24

-8

kiruha [24]

Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.

I would use a fraction bar.

Now, the problem asks us to compare

the number of boys to the number of girls.

We know that there are 12 boys

and we know that there are 15 girls.

So our ratio is 12/15.

However, this can be reduced to 4/5.

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?
Lana71 [14]

Answer:

Given the equation: 2(x-3)+9=3(x+1)+x

Distributive property of multiplication states that when a number is multiplied by the sum of the two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,

a \cdot (b+c) = a\cdot b+a\cdot c

Now, using distributive property to LHS and RHS, we get

2x-6+9=3x+3+x

Combine like terms on RHS;

2x-6+9 = 4x+3

or

2x+3 = 4x+3

Subtract 3 from both sides of an equation;

2x+3-3 =4x+3-3

Simplify:

2x = 4x

or

4x-2x =0

2x = 0

⇒ x =0

Therefore, the value of x in the given equation

2(x-3)+9=3(x+1)+x is 0.
