Answer:
71
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 456
6x + 30 = 456
add -30 to each side
6x = 426
divide each side by 6
x = 71
Divide both sides by f then cancel out
I’m pretty sure it is B
Hope I helped.
Seriously: add the x's divide by 2, add the y's divide by 2, bob's your uncle. you have the midpoint.
