For what values of x is x2+2x=24 true?

JulijaS [17]

Answer:

$x=-6$ and $x=4$

Step-by-step explanation:

We must solve the quadratic equation to find the values of x that satisfy equality

$x^2+2x=24$

Subtract 24 on both sides of equality

$x^2+2x-24=24-24$

$x^2+2x-24=0$

Now we factor the quadratic equation

Identify two numbers that when you add them you get as a result 2 and when you multiply them you get as a result -24

The numbers sought are: 6 and -4

So the factors are:

$(x+6)(x-4)=0$

Finally note that the solutions are:

$x=-6$ and $x=4$

The volume of a cube is 27 cubic yards. Find the side length.

IceJOKER [234]

Since all sides of a cube are equal...,

Let one side length of a cube be (z)

;Volume = z × z × z

;Volume = z^3

; 27 = z^3....where we then say that..,

; z(side length) = cube root of (27)

; Hence..., Side Length = 3 yards
