Answer:
see below
Step-by-step explanation:
t = 7m
Let m = 6
t = 7*6 = 42
Let m = 8
t = 7*8
t = 56
A. -3x+5+7-4x
-3x-4x+5+7
-7x+12
-7x+12-5x+17
-7x-5x+12+17
-12x+29
B. -5*(x+2)= -5x-10
-6x-1+ (-5x-10)= -6x-5x-1-10=
-11x-11
For circumference it’s 12x3.14= 37.68
Step-by-step explanation:
x+30°=4x(inscribed angle is equal to its arc)
4x-x=30°
3x=30°
x=30/3
x=10°
hope it helps.
B is the most misleading because the amount of miles decreases. This would mean that the racer would have gone forward, then backward, then forward again.
