Answer:
C. 101 - 5(n - 1)
Step-by-step explanation:
d = (26 - 71)/(16 - 7)
d = -45/9
d = -5
a7 = a1 + (7-1)(-5)
71 = a1 - 30
a1 = 101
an = 101 + (n - 1)(-5)
an = 101 - 5(n - 1)
G is<span> the centroid it means that BG/FG=2 (G divides the median with this ratio)
3x+6/2x-1=2
3x+6=4x-2
x=8
then AG=26 then GE=13 so AE=39</span>
![\frac{9(14+16)*2-(8*4+12*9)}{40} \\ \frac{(9*2)(14+16)-[(8*4)+(12*9)]}{40}\\ \frac{(18*30)-(32+108)}{40}\\ \frac{540-140}{40}\\ \frac{400}{40}\\ 10](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%2814%2B16%29%2A2-%288%2A4%2B12%2A9%29%7D%7B40%7D%20%5C%5C%0A%5Cfrac%7B%289%2A2%29%2814%2B16%29-%5B%288%2A4%29%2B%2812%2A9%29%5D%7D%7B40%7D%5C%5C%0A%5Cfrac%7B%2818%2A30%29-%2832%2B108%29%7D%7B40%7D%5C%5C%0A%5Cfrac%7B540-140%7D%7B40%7D%5C%5C%0A%5Cfrac%7B400%7D%7B40%7D%5C%5C%0A10)
So the expression is equal to
10.
Answer:
Width - 12ft Length - 30ft
Step-by-step explanation:
Width is 12ft
Length is 30ft
Depth is 6ft
The length, 30ft, is 2.5 times longer than the width which is 12 ft which confirms the two dimensions to be correct.
When you multiply all three of the dimensions of the swimming pool you will get 2940 cubic feet
