Answer:
Step-by-step explanation:
4. -3(2x + 6) = -6x - 18
5. -3x - 9= -3(x + 3)
6. 5x - 25y = 5(x - 5y)
Answer:
I think it's measure of distance.
let me know if that is right
(4n+1)=(2n-9)
the sum of four times a number and one is equal to the difference of twice the number and 9
Answer:
1
Step-by-step explanation:
1 times anything is itself
you're welcome
1st angle - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
