Answer:

3x+12

Step-by-step explanation:

Expanding is basically the opposite of simplifying an equation, in order to expand you just multiply everything out

Here we have

$3(x+4)$

which just means

$3*(x+4)$

which is

$3*x+3*4\\=3x+12$

PLEASE HELP ME The length of the one of the legs of a right triangle is 8m and the hypotenuse is 12m. Which of the following cho

Bas_tet [7]

Answer:

The length of the other leg is 8.94 m.

Step-by-step explanation:

Given that,

Hypotenuse of a right triangle is 12 m

The length of the one of the legs of a right triangle is 8 m

We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

$H^2=b^2+h^2$

H = hypotenuse = 12 m

b = base = 8 m

$h^2=H^2-b^2\\\\h^2=12^2-8^2\\\\h=\sqrt{80}\\\\h=8.94\ m$

So, the length of the other leg is 8.94 m.

Help me as quick as possible <br> 11x+4y=12<br> 9x-4y=8<br> Solve it with elimination method

Firdavs [7]

Answer:

x = 1, y = 1/4

Step-by-step explanation:

$11x + 4 y = 12 \ \ \ ---( 1)\\9x -4y = 8 \ \ \ - - - (2)\\\\(1) + ( 2 ) => 20x + 0 = 20\\\\$

$=> x = 1$

Substitute x = 1 in ( 1 ) :

$11 + 4y = 12\\4y = 12 - 11\\\\y =\frac{1}{4}$
