tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic e

Bond [772]

Answer:

$x^2-\dfrac{9}{2}x-9=0$

Step-by-step explanation:

The solutions of a quadratic equation are :

x = -3/2 and x = 6

or we can write it as :

$x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0$

Multiplying both values,

$(x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0$

Hence, the required quadratic equation is $x^2-\dfrac{9}{2}x-9=0$ .

<h3>Answer: Choice B</h3>

angle B = 118, a = 17, c = 18

==========================================================

Explanation:

Use the given angles to find angle B.

A+B+C = 180

B = 180-(A+C)

B = 180-(30+32)

B = 118

Now use the law of sines to find side 'a'

Make sure your calculator is in degree mode.

a/sin(A) = b/sin(B)

a/sin(30) = 30/sin(118)

a = sin(30)*30/sin(118)

a = 16.9885507603356

a = 17

Follow similar steps to find side c

c/sin(C) = b/sin(B)

c/sin(32) = 30/sin(118)

c = sin(32)*30/sin(118)

c = 18.005120638611

c = 18

6. Consider the inequality 12<-3 (x + 4). Which value of x is part of the solution set of this inequality?

Naily [24]

Answer:

-8

Step-by-step explanation:

12<-3 (x + 4)

1. distribute to the -3 to the x and 4 and should get

-3*x = -3x

-3*4 = -12

12< -3x - 12

2. now you get rid of the common factors which is -12 so add 12 to both sides and should get

-12+12=0

12+12=24

24< -3x

3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get

-3x/-3= x

24/-3= -8

-8<x
