Answer:
16.03
Step-by-step explanation:
Using the given formula, replace sa with the given surface areas and solve for s:
Surface area = 1200
s = √1200/6
s = √200
s = 14.142
Surface area = 768
s = √768/6
s = √128
s = 11.313
Difference:
14.142 - 11.313 = 2.829 inches
Round answer as needed.
Answer:
4 sqrt(2) - sqrt(70)
Step-by-step explanation:
Simplify the following:
(4 sqrt(14) + 4 sqrt(10)) (3 sqrt(7) - 4 sqrt(5))
Factor 4 out of 4 sqrt(14) + 4 sqrt(10) giving 4 (sqrt(14) + sqrt(10)):
4 (sqrt(14) + sqrt(10)) (3 sqrt(7) - 4 sqrt(5))
(sqrt(10) + sqrt(14)) (3 sqrt(7) - 4 sqrt(5)) = sqrt(10) (-4 sqrt(5)) + sqrt(10)×3 sqrt(7) + sqrt(14) (-4 sqrt(5)) + sqrt(14)×3 sqrt(7) = -20 sqrt(2) + 3 sqrt(70) - 4 sqrt(70) + 21 sqrt(2) = sqrt(2) - sqrt(70):
Answer: 4 sqrt(2) - sqrt(70)
x first so five to the left so it's negative and if each gridline is .5 and were are 5 gridlines aver then .5*5 so -2.5 then y is up so positive and 3 lines so .5*3 so 1.5 so coordinate is (-2.5,1.5)
