Answer:
He needs to run 7 miles per day. 217/31 = 7m
Step-by-step explanation:
X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
3x+x= 180°(straight angle)
4x= 180°
x= 180/4
x= 45°
Answer:
I’m not sure really but the first one is 103 or 110
Step-by-step explanation:
7(5)-12(5)-5=-45+15
-30 = -30
answer= B. x=5
