3X-1=11

(3*x)-1=11

x=4

(3*4)-1=11

(12)-1=11

so sub w/ all X

X2+X

(4*2)+4

(8)+4

answer= 12If you with X2 mean X²:

4²+4=20Q: 3X - 1 equals 11 what is the value of X2 plus X?

At x = 3, the value of F(x) = 3x + 2 is the value 11, which graphs to the point (3, 11).

3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)

It is an equation and the value of x is 13/3

If: 3x-1 = 11 Then: 3x = 11+1 So: x = 12/3 = 4

- If 3X - 1 = 11, what is the value of X^2 + X?

At x = 3, the value of F(x) = 3x + 2 is the value 11, which graphs to the point (3, 11).

The value of x is -4

3x-1 = 11 3x = 11+1 3x = 12 x = 4 Therefore: x2+2 = 18

It is an equation and the value of x is 12

3x-1=11 solves to x=4. Plug in 4 to get 42+4. The answer is 20.

3x-1=11 x=4 x^2+x=20

I suspect the answer depends on the value of t.

3x-1=11 3x = 12 x = 4 Then, x^2 +x = 20.
