Factor 4x^2-4x-8 Please help

Mathematics
2 answers:
gavmur [86]3 years ago

Answer:

4x² - 4x - 8 can be factored into 4(x - 2)(x + 1)

Step-by-step explanation:

First, we can factor out 4, as all terms are divisible by that:

4x² - 4x - 8

= 4(x² - x - 2)

Now we need to find two numbers that are are factors of -2, but add up to -1.  -2 and 1 meet that condition, so let's split the middle term into those coefficients:

=4(x² + x - 2x - 2)

= 4( x(x + 1) - 2(x - 1) )

= 4(x - 2)(x + 1)

Answer:

4(x+1)x(x-2)

Step-by-step explanation:

Step 1: factor it

4(x^2-x-2)

Step 2: re write the expression and make -x as a difference

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

Step 3: factor out x from the expression

4(x *(1+1)-2(x+1))

Step 4: factor out x+1 from the expression

4(x+1) x (x-2)

Das it hope you have a good day lol

Can someone help geometry is confusing
NikAS [45]

<LMP and <NMP are supplementary angles so sum = 180

<LMP +  <NMP = 180

(-16x + 13) + ( - 20x + 23) = 180

-16x + 13  - 20x + 23 = 180

-36x + 36 = 180

-36x = 144

    x = -4

<LMP = -16x + 13 = -16(-4) + 13 = 77

<NMP = - 20x + 23 = - 20(-4)  + 23 = 103

Answer

<LMP  = 77°

<NMP  = 103°

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
JulijaS [17]

Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

   = (1÷3)×(5×7)×9

   = 105 cm³

Then

The density = mass/volume

                    = 60÷105

                    = 0.571428571429
