Cube has 6 faces that are square
area of square=side^2
side=8
SA=6s^2
SA=6(8^2)
SA=6(64)
SA=384 ft^2
Two ways:
1) guess factors(trial and error)
2) use quadratic formula.
If you use this method then a = -3, b = -6 and c = -1
x = -b +/- [sqrt(b^2 -4ac)/2a]
substituting a, b, and c into our equation we get:
x = - (-6)+/- [sqrt ((-6)^2) - 4(-3)(-1))/2 (-3)]
x = + 6 +/- [sqrt (36 -4 (3)/-6)] if I didnt make a mistake in my signs
x = + 6 +/- [sqrt (36 -12)/-6)]
x = 6 +/- [sqrt (24)/-6] but sqrt 6 x sqrt of 4 = sqrt 24 hence
x = 6 +/- [ sqrt 6 x sqrt 4 /-6] that is:
x = 6 +/- [sqrt 6 x 2 /-6 ]
so x = 6 + [sqrt 6 x 2/-6] and x = 6 - [sqrt 6 x 2/-6]
Answer: No
Step-by-step explanation:
I can’t think of one but if you have a pegboard there is a formula called Pick’s Formula
Answer: 19 + (-27)
Step-by-step explanation:
Time from October 5 to January 16
T=26+30+31+16=103 days
I=1870*0.11*103/365=58.05
