90 < [( n + n + 2 + n + 4) / 2] < 105
90 < (3n + 6) / 2 < 105
3n + 6 > 180 and 3n + 6 < 210
n > 58 , n < 68
58 < n < 68 answer
Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/( -3 - -3)
= ( -4-4)/( -3+3)
= -8/0
When we divide by zero, the answer is undefined so the slope is undefined
h=9
A=((a+b)/2)h
234=((32+20)/2)h
234=(52/2)h
234=26h
9=h
Set 40 = 5x + 10
Subtract 10 on both sides, then divide 30 by 5
x = 6
