X-36+12x=224 due 15 min ago

Answers

Answer:

x = 20

Step-by-step explanation:

Starting equation: x - 36 + 12x = 224

Reorder: 12x + x (as there is no negative sign in front of the x) - 36 = 224

Add common terms: 13x - 36 = 224

Subtract (in this case add) common term to isolate variable: 13x + 36 = 224 + 36

Isolate variable by dividing both sides by 13: 13x = 260

Solve: x = 20

Use the zero product property to find the solutions to the equation x2 – x – 6 = 0.x = –3 or x = –2
x = –3 or x = 2
x = –2 or x = 3
x = 2 or x = 3

Answers

x² - x -6 = 0
Δ = b² -4ac = (-1)² -4·1·(-6) = 1 + 24 = 25
x₁= (-b + √Δ)/(2a) = (1 + √25)/2·1 = (1+5)/2 = 6/2 = 3
x₂= (-b - √Δ)/(2a) = (1 - √25)/2·1 = (1-5)/2 = -4/2 = -2

x=3 or x=-2

we know that

The Zero Product Property states that if $a*b = 0$ , then either $a = 0$ or $b = 0$ (or both)

we have

$x^(2) -x-6=0$

rewrite the expression

$x^(2) -x-6=(x+3)(x-2)$

$(x+3)(x-2)=0$

$(x+3)=0\nx=-3$

$(x-2)=0\nx=2$

therefore

the answer is the option

x = –3 or x = 2
