Answer:

P = 2x + 2y + 14

Step-by-step explanation:

Length (L) = x + 8 units

Width (W) = y - 1 units

Perimeter (P) = 2L + 2W

P = 2(x + 8) + 2(y - 1)

P = 2x + 16 + 2y - 2

P = 2x + 2y + 16 - 2

P = 2x +2y + 14

Bethany says that 3x+6+x and 3(x+2) and equivalent expressions. She used substitution to support her answer. Explain what Bethan
Vinvika [58]

She forgot about the final x at the end, because the first expression is 3x+6+x, and the second one is 3(x+2). The second one expands to 3x+6, but it doesn't have the final term at the end.

Also, 3 is not really a factor of x (technically it could be because x in unknown, but in terms of like terms and stuff it isn't) so you can't take a 3 out of x (unless you leave it as 1/3x I guess).

Anyway, yeah she forgot about the final x and therefore the factor she took out is incorrect anyway. She also could've simplified the first expression so that it became 4x + 6

X+y+z=3<br> x-y+z=2<br> x+y-z=1
Dima020 [189]

Answer:

Step-by-step explanation:

I'm assuming you are solving this system for x, y, and z.  Do it this way:

Combine the first 2 equations and the second 2 equations and eliminate the y's.  The first 2 equations:

x + y + z = 3

x - y + z = 2

which solves to

2x + 2z = 5

The second 2 equations:

x - y + z = 2

x + y - z = 1

which solves to

2x = 3 so

x = 3/2 or 1.5

Now sub that x value into the bold equation above to get:

2(1.5) + 2z = 5 and

3 + 2z = 5 and

2z = 2 so

z = 1

Now we plug back in to solve for y:

1.5 + y + 1 = 3 and

2.5 + y = 3 so

y = .5

The solution set then is (1.5, .5, 1) or in fraction form:

(\frac{3}{2},\frac{1}{2},1)
