How to factor 6x^2-48x-120

1 answer:

6 0

Hello there!

Simply find a common term that they all have!

So they can all be divided by 6, right? So let's take a 6 out.

6 (x^2-8x-20)

Now factor the terms in the parenthesis!

6 (x-10) (x-2)

^ This is NOT your answer!!

Tip: When looking at (x^2-8x-20), look at the middle term. (-8x). Since it's negative, either (x-10) or (x-2) can be negative.

Which one is negative? Well, is the 8 positive or negative? Since the 8 is negative, the parenthesis bigger number (x-10) will be negative!

So it'll be:

6 (x-10) (x+2)

ALWAYS double check your answer by foiling! :)

Hope this helped!

How many square inches of paper did Benjamin use to wrap the box

Answer:

$2,124\ in^{2}$

Step-by-step explanation:

we know that

The surface area of a rectangular prism is equal to

$SA=2B+Ph$

where

B is the area of the base

P is the perimeter of the base

h is the height

In this problem we have

$B=18*24=432\ in^{2}$

$P=2(18+24)=84\ in$

$h=15\ in$

substitute

$SA=2(432)+(84)(15)=2,124\ in^{2}$

Katen [24]

Answer:

14 inch ^2

Step-by-step explanation:

Area of a trapezium= (a+b) 2 times h

so side a= 5 inches

side b= 9 inches

then times by 2 times the height (2)

you can rearrange the formula to this- a + b/ 2 times height.

5+9/2 times 2= 14

I hope this helps, have a lovely day.

3. Find the least number should be subtracted 9240 to make perfect square.

Elenna [48]

Find the square root of 9240 = √9240 = 96.125... now, take the whole number in the square root of 9240 which is 96 and now square this number so, 96² = 9216. Take the 9216 and subtract it from 9240 which is 24.
