Your friend claims that there is not enough information given to find the value of x.Is your friend correct?

Choose the quadratic equation that has a leading coefficient of 1 and solutions 3 and -2.

ss7ja [257]

Answer:

Option D $x^{2} -x-6=0$

Step-by-step explanation:

Verify each quadratic equation

case A) we have

$x^{2} +x+6=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} +(3)+6=0$

$18=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case B) we have

$x^{2} -x-5=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} -(3)-5=0$

$1=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case C) we have

$x^{2} +x+5=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} +(3)+5=0$

$17=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case D) we have

$x^{2} -x-6=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} -(3)-6=0$

$0=0$ ----> is true

therefore

x=3 is a solution of the quadratic equation

For x=-2

$(-2)^{2} -(-2)-6=0$

$4+2-6=0$

$0=0$ ----> is true

therefore

x=-2 is a solution of the quadratic equation

Given the equation P = 2w + 2l solve for w.

bagirrra123 [75]

This equation cannot be solved to get a single number. Instead just use normal algebra skills to get the w by itself by subtracting 2l from both sides and then dividing by 2.

If I look in my closet before I go to school, I have 5 pants

BigorU [14]

Answer: 180 possible outfits

Step-by-step explanation:

so basically you're gonna multiply each option by the other, making 5 different ways you could combine pants with that one type of shirt and so on. That gives you 5 x 12 x 3 which is 180
