2 1/4 = 2 3/12
16 2/3 = 16 8/12
16 8/12 + 2 3/12 = 18 11/12
Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18

Answer:
Step-by-step explanation:
-1 1 3 5 7 9 11
That's the answer. If you need a method or a formula, that's a little harder.
L = a + (n - 1)*d
a = -1
L = 11
n = 7
or n is the hard part. If you have 5 means, then you have 6 spaces. So n must be 7 in all
11 = -1 + (7 - 1)*d add 1 to both sides. Combine the brackets
11+1 = -1+1+ 6*d
12 = 6d divide by 6
12/6 = d
2 = d
What this tells you is that each term has 2 added to it to get to the next one.
Answer:
(4x -3)(√3x -1)(√3x +1)
Step-by-step explanation:
Your factoring is correct for integers. However the quadratic term can be factored further using irrational coefficients. It is the difference of the squares of (√3)x and 1, so can be factored as such.
12x³ -9x² -4x +3 = 3x²(4x -3) -(4x -3) = (3x² -1)(4x -3)
= ((√3)x -1)((√3)x +1)(4x -3) . . . . . . further factoring the difference of squares
