Answer:
x=40
Step-by-step explanation:
30x-215=985
Add 215 to each side
30x -215+215 =985+215
30x = 2100
Divide each side by 30
30x/30 = 1200/30
x=40
I repaired the damage from car accidents.
Bro- basically so the first option a- right? So a is 4-8-12-16. And B is just that times two so the third option down
n is an integer, so 2n+1 is also an integer. 8s+1 is equal to the square of 2n+1, so it's a square number.
2n+1 is an odd integer for any value of n. The square of an odd integer is always an odd integer. Therefore 8s+1=(2n+1)² is odd.
8s+1 is an odd square number.
Your answer would be B. It does not satisfy both equations. It satisfies the y>2x-1 because 0 is greater than -1. But for the other equation 0 is not less than -4.
