Answer:
Answer:
2x • (x2 - 2xy + 5x - 10y)
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
(((2•(x3))+(10•(x2)))-(22x2•y))-20xy
Step 2 :
Equation at the end of step 2 :
(((2 • (x3)) + (2•5x2)) - 22x2y) - 20xy
Step 3 :
Equation at the end of step 3 :
((2x3 + (2•5x2)) - 22x2y) - 20xy
Step 4 :
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
2x3 - 4x2y + 10x2 - 20xy =
2x • (x2 - 2xy + 5x - 10y)
Final result :
2x • (x2 - 2xy + 5x - 10y)
Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
3x + 7 = 2x + 1
Subtract 7 on both sides to leave 3x alone
3x = 2x - 6
Subtract 2x on both sides to have X on one side only
3x - 2x = x
x = -6
I'm not entirely sure as to what Dcmam is but there is really not much else you can do to find this value of x, it's as simple as that.
Answer:
