Answer:
Step-by-step explanation:
Circumference = πd = 12
d = 12/π cm
5/6*x + 2= 4/5*x -3
5/6*x - 4/5*x = -3 -2
x*(5/6-4/5)= -5
x*(25/30-24/30)=-5
x*1/30= -5
x/30=-5
x= -30*5
x= -150

Step-by-step explanation:
Answer: 3x⁴ + x + 7
<u>Step-by-step explanation:</u>
(5x⁴ - 3x² + 7x - 10) - (2x⁴ - 3x³ + 6x - 17)
Distribute the negative to the second expression, which means "change all of the signs" and then add the two expressions.
( 5x⁴ - 3x² + 7x - 10)
+ <u>(-2x⁴ + 3x³ - 6x + 17)</u>
= 3x⁴ + 0x³ + 1x + 7
= 3x⁴ + x + 7
Note: If you need to show work for distributing the negative sign, multiply each term of the second expression by -1.
