Answer:

AC ; BC ; AB

Step-by-step explanation:

Given the triangle attached :

Using visual cue, we can detect the and order the length of the sides of the triangle from greatest to least as follows :

Greatest = AC

Followed by BC ;

Then ; AB

Hence. We have ;

AC ; BC ; AB

Y=-2|x+2|-4 i need to find y intercept and the x intercept

NeTakaya

Answer:

x-int: ∅

y-int: (0,-8)

Step-by-step explanation:

To find the x and y-intercept, simply plug in zero for x and y:

$0=-2|x+2|-4\\4=-2|x+2|\\-2=|x+2|\\$

Because an absolute value cannot be equal to a negative, there is no x-intercept.

$y=-2|0+2|-4\\y=-2|2|-4\\y=-4-4\\y=-8$

Hope it helps :)

Total surface area of a cube is 1014cm^2. It's volume will be :

rewona [7]

Answer:

$V=2197\ cm^3$

Step-by-step explanation:

<u>Surface Area and Volume of a Cube</u>

Given a cube of side length a, the surface area is:

$A = 6a^2$

The volume is calculated as:

$V=a^3$

It's given the surface area of a cube:

$A=1014\ cm^2$

We can find the side length a by solving for a:

$\displaystyle a=\sqrt{\frac{A}{6}}$

$\displaystyle a=\sqrt{\frac{1014}{6}}$

$\displaystyle a=\sqrt{169}$

a = 13 cm

Now compute the volume:

$V=13^3$

$\boxed{V=2197\ cm^3}$

Answer: a) 2197 cm^3
