The trick here is to notice that all 3 terms can be div. by 2:

2(x^2 + x - 12)

Note that -12 factors into -3 * 4 or -4 * 3.  Thus,

x^2 + x - 12 = (x-4)(x+3), and so <span>2x2 + 2x − 24 = 2(x-4)(x+3).</span>

Answer:

2(x − 3)(x + 4)

Step-by-step explanation:

We have to factor the expression 2x^2+2x-24

Factor out GCF which is 2

2(x^2+x-12)

We can write the middle term as : x = 4x-3x

2(x^2+4x-3x-12)

Now, we factor out GCF as follows

2(x(x+4)-3(x+4))

Now, factored out the common term

2((x+4)(x-3))

First option is correct.

Factored form is given by 2(x − 3)(x + 4)

For every 4 gallons of green paint he uses 3 gallons of blue paint. Drag the correct number of each type of paint into the box t
Inga [223]

Answer:

Amount of green color used =

\dfrac{64}{7}\text{ gallons}

Step-by-step explanation:

We are given the following in the question:

Every  4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}

Amount of shade = 16

Amount of green paint = 4x

Amount of blue paint = 3x

Thus, we can write:

4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}

Amount of green color used =

4x = 4\times  \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}

Amount of blue paint used =

3x = 3\times  \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}

What figure has a perimeter of 22 units?
Sav [38]
Without knowing the shape selection you have i cant really say anything.  But with a square you wouldnt have any whole numbers, nor would a triangle give you whole number, than again no shape that i can think of would give whole numbers.

What is the solution of the equation (4x + 3)2 = 18?
saveliy_v [14]

Hello!

First of all, let's undo the parentheses.

8x+6=18

Now we subtract 6 from both sides.

8x=12

Finally, we divide both sides by 8.

x=1.5

I hope this helps!
