Answer:

x < 50

Step-by-step explanation:

No more means that it cannot equal 50. Therefore we can remove the 1st two options.

We now have the 3rd option and 4th option to choose from.

The 4th option is incorrect because the inequality is saying that a number is greater than 50.

∴ x < 50 is our answer.

According to postal regulations, the girth plus the length of a parcel sent by fourth-class mail may not exceed 108 in. What is

solmaris [256]

Answer:

11,664 in³

Step-by-step explanation:

For a square side length of x, the girth is 4x and the length of the parcel is then allowed to be up to 108-4x.

The total volume is the product of the edge lengths, so is ...

V = (108 -4x)(x²) = -4x³ +108x²

This will be a maximum where its derivative is zero:

dV/dx = -12x² +216x = 0 = -12x(x -18)

This is zero for x=0 and for x=18.

The maximum volume parcel is 18 in by 18 in by 36 in, and has a volume of ...

(18 in)(18 in)(36 in) = 11,664 in³

Expand than simplify: -4(-2p+5)

Snowcat [4.5K]

First what we do since we are expanding the expression is do

-4*-2p
=8p

Then,

-4*5
=-20

Now since there are no like terms we get our final answer which is...

*8p-20*

What is the product of (9t-4)(-9t-4)

Ronch [10]

<span>(9t-4)(-9t-4)

using the FOIL :

9t * -9t = -81 t^2
9t * -4 = -36 t
-4 * -9t = 36 t
-4 * -4 = 16
-----------------------add up and simplify

$-81 t^2 -36 t + 36 t +16 = -81 t^2 +16$ </span><span />
