Step-by-step explanation:
I think its 2x +3x=21 because you can plug in the numbers?
Answer:
C
Step-by-step explanation:
D to c = 15, DtoB =17 so Cto B= 17
and A to C =34
The answer would be add 13 because
12 + 13 would be 25, 25 + 13 would be 38. Hope this helps
6/5 because flip the second number and multiply when dividing fractions.
9x²-0x-4
=9x²-4
=(3x-2)(3x+2) is the factor form of 9x²-0x-4
Solve for x:
3x-2=0
Add 2 to each side
3x-2+2=0+2
3x=2
Divided 3 to each side
3x/3=2/3
x=2/3
Or
3x+2=0
Subtract 2 to each side
3x+2-2=0-2
3x=-2
Divided 3 to each side
3x/3=-2/3
x=-2/3. Hope it help!
