Answer:12
Step-by-step explanation:
I think it should be x(ax +b) + c. Not sure though.
Answer:
2*(5x - 2) + 2*(3x+1) ; Perimeter = 62 centimeters
Step-by-step explanation:
2*(5x - 2) + 2*(3x+1) = 10x - 4 + 6x + 2
= 16x -2
If x = 4 , then Perimeter = 16*4 - 2 = 64 - 2 = 62 cm
He final number is 5 times the original number
Answer:
x=-1/2
Step-by-step explanation:
Move -2x to the other side by adding 2x on both sides:
12x+8=2
Move 8 to the other side by subtracting 8 on both sides:
12x=-6
Divide by 12 on both sides:
x=-1/2
Hope this helps!
