Answer:

x = 0.

Step-by-step explanation:

I guess you need to solve this for x:

-3(2x - 3) = 6x + 9 Distribute the -3:

-6x + 9 = 6x + 9 Subtract 6x from both sides:

-6x - 6x + 9 = 6x - 6x + 9

-12x + 9 = 9 Subtract 9 from both sides

-12x + 9 - 9 = 9 - 9

-12x = 0

x =0.

1.Morgan drives 24 miles due north, then drives 7 miles due east from home to work. What is the distance between Morgan’s home a

Naily [24]

Answer:

1) 25 miles

2) 20 m

Step-by-step explanation:

Number 1 is going to be

$a^{2} + b^{2} = c^{2}$ because it's a right triangle

$24^{2}$ + $7^{2}$ = $c^{2}$

625 = $c^{2}$

c = 25 mile

Number 2 uses the same process, but changing to using C instead of A

a^2 = c^2 - b^2

a^2 = 625 - 225

a = \sqrt(400)

a = 20m

How do you factor this? x^{2} + 5 x- 9 = ?

Oksanka [162]

$x^2+5x-9\\\\a=1;\ b=5;\ c=-9\\\Delta=b^2-4ac\\\\\Delta=5^2-4\cdot1\cdot(-9)=25+36=61 > 0\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\\\\sqrt\Delta=\sqrt{61}\\\\x_1=\dfrac{-5-\sqrt{61}}{2\cdot1}=\dfrac{-5-\sqrt{61}}{2}\\\\x_2=\dfrac{-5+\sqrt{61}}{2\cdot1}=\dfrac{-5+\sqrt{61}}{2}\\\\x^2+5x-9=\left(x-\dfrac{-5-\sqrt{61}}{2}\right)\left(x-\dfrac{-5+\sqrt{61}}{2}\right)$
