Can u guys helpme please!!!
Answer:
x³-5x²+4x
Step-by-step explanation:
1. Expand.
(x²-4x)(x-1)
2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.
x³-x²-4x²+4x
3. Collect like terms
x³+(-x²-4x²)+4x
4. Simplify
x³-5x²+4x
Hope this helps, have a BLESSED and wonderful day! c:
Okay well I do it like this. 3+8=11. I put a 1 down and carry the other. so I do 7+0+1=8 so now I have 81, and last I do 6+3=9. so the answer would be 981.
Have a nice day!
Answer:
54
Step-by-step explanation:
Diagonals are perpendicular so
2x+ 90 + 3x = 180 since this forms a triangle
Combine like terms
5x+ 90 = 180
Subtract 90 from each side
5x +90-90 =180-90
5x = 90
Divide each side by 5
5x/5 = 90/5
x =18
We want to find Angle ABD
ABD = 3x = 3*18 = 54
