I'm confused what are you suppose to do
Answer:
x=2
Step-by-step explanation:
10x+4=2x+20
10x-2x=20-4
8x=16
x=2
Wat r u asking about this problem
Find the quotient: (25c^4 + 20c^3) ÷ 5c5c^3+4c^2.
If you want to use integer tiles to find the product of 2(-5), think of it as you having 2 groups of 5 negative tiles, that is
-1 -1
-1 -1
-1 -1
-1 -1
-1 -1
Think of it as you having each of the -1 inside it's distinct tile. Now adding up these tiles you have -10.
Therefore 2(-5) is -10 using integer tiles.
If we are to use the number line, first draw your number line, then think of it as jumping twice while each jump is -5 big.
So the first jump from 0 will land on -5 and the second jump will land on -10 and that is the required answer using the number line.
