Answer:
(5,2,2)
Step-by-step explanation:
-3x+4y+2z = -3
2x-4y-z=0
y = 3x-13
Multiply the second equation by 2
2*(2x-4y-z)=0*2
4x -8y -2z =0
Add this to the first equation to eliminate z
-3x+4y+2z = -3
4x -8y -2z =0
-------------------------
x -4y = -3
Take the third equation and substitute it in for y
x - 4(3x-13) = -3
Distribute the 4
x - 12x +52 = -3
Combine like terms
-11x +52 = -3
Subtract 52 from each side
-11x +52-52 = -3-52
-11x = -55
Divide by -11
-11x/-11 = -55/-11
x=5
Now we can solve for y
y =3x-13
y =3*5 -13
y = 15-13
y=2
Now we need to find z
2x-4y-z=0
2(5) -4(2) -z=0
10-8 -z=0
2-z=0
Add z to each side
2-z+z= 0+z
2=z
x=5, y=2, z=2

Answer:
48 ft^2
Step-by-step explanation:
5.5 times 6 equals 33 (larger square part)
2.5 times 6 equals 15 (two triangles combined so you dont have to 1/2)
Answer: 17+ 16 = 33
Good luck !

sorry I'm confused boy sorryy
(n) stands for natural number. Natural numbers are counting numbers such as 1, 2, 3, 4, 5, 6, 7 etc...
So the first term in the sequence would be:
T(1)=1^2 + 3 = 1 + 3 = 4
Answer:
4
