Answer:

x=4

Step-by-step explanation:

Pentagon's sum of interior angle is 540°

let's add all the given degrees

100+20x+16x+16+140+160-5x=540

Collect like terms

100+16+140+160+20x+16x-5x=540

416+31x=540

31x=540-416

31x=124

x=124/31

x=4```

What is the solution to the system of equations? -3x-y+z=6 -3x-y+3z=0 x-3z=3
valentina_108 [34]

Answer:X/3X=3

We move all terms to the left:

X/3X-(3)=0

Domain of the equation: 3X!=0

X!=0/3

X!=0

X∈R

We multiply all the terms by the denominator

X-3*3X=0

Wy multiply elements

X-9X=0

We add all the numbers together, and all the variables

-8X=0

X=0/-8

X=0

Can somebody please help me find the area of each graph with the base and height? for 12 points
UNO [17]

To find area you

Multiply base times height.

Bh=A

So multiply the base times the height of the graph?

So 6 times 6 equals area.

Of course since we are dealing with the 4 quadratics 6 can be negatives or positive.

Whether it’s negative or not area is area.

If you’re finding the coordinates shapes area, sorry I have no idea

I am doing this too but mines definitely different
