For this example all you have to do is subtract -4/5 from both side

So the answer is 51/5=x

(k^2-6k^4)-(3k^4+k^2+2)

jeka57 [31]

Step-by-step explanation:

Vamos simplificar passo a passo.

k2-6k4-(3k4+k2+2)

Distribua o sinal negativo:

=k2-6k4+-1(3k4+k2+2)

=k2+-6k4+-1(3k4)+-1k2+(-1)(2)

=k2+-6k4+-3k4+-k2+-2

Combine os termos semelhantes:

=k2+-6k4+-3k4+-k2+-2

=(-6k4+-3k4)+(k2+-k2)+(-2)

=-9k4+-2

Responda:

=-9k4-2

dusya [7]

Imagine taking a cube and slicing it open from one of the corners.

The exposed area of the cube would be a triangle. See the image for reference.

Can anyone help?? Please

3O=12/3 Divide both sides by 3.
/3

O=4

♢+2=5(4)
♢+2=20
 -2 -2 Subtract 2

 ♢=18

2(4)+18=2∆
8+18=2∆
26=2∆
/2 /2 Divide by 2

∆=13

Solve a, b, c, & d please & I will mark you as Brainliest.

Answer:

Step-by-step explanation:

$a) -2x-3y=5\\-5x+3y=-40\\-7x=-35\\x=5, y=-5\\\\b)5x+6y=-14\\x-2y=10\\Considering\ equation\ 2,\\3(x-2y)=3(10)\\3x-6y=30\\Hence,\\5x+6y=-14\\3x-6y=30\\8x=16\\x=2, y=-4\\\\c) -3x+3y=21\\-x-5y=-17\\Considering\ equation\ 2,\\3(-x-5y)=3(-17)\\-3x-15y=-51\\Hence, subtracting\ both\ the\ equations\ we\ get,\\-3x+3y=21\\3x+15y=51\\18y=72\\y=4, x=-3$

d) Let the cost of one group lesson be x and one private lesson be y

$12x+2y=110\\10x+3y=125\\By\ multiplying\ the\ first\ equation\ with\ -1.5\ in\ this\ system\ we\ get,\\-1.5(12x+2y)=-1.5(110)\\-18x-3y=-165\\Hence,\ by\ adding\ both\ the\ equations\ we\ get,\\-18x-3y=-165\\10x+3y=125\\-8x=-40\\x=5,y=25$
