4 ( x+7)(x+2) expand
4 ( x^2 +9x + 14)
4x^2 + 36x + 56 is a bowl shaped parabola max value = + infinity
MIN value occurs at - b/ 2a = - 36/8 = - 4.5 use this value of 'x' in the equation to calculate the min value
Nothing happens.
(-3/4) * (-12) = 36/4 = + 9
4 pm less 1 hr 45 minutes = 2:15 pm
3 s + 7 h = 32 s = shoes h= hand grenades
6 s + 2 h = 22 Multiply first equation by -2 and add to second equation to get :
-12 h = -42
h = 3.5 pounds
Oh...really?
2x = 40 divide both sides of the equation by 2
x = 20
.25 x = .15 (12)
x=7.2 liters of .25 bleach required..... the REST of the 12 liters would be water (4.8 not 7.8)
40 coins
nickles = n value = 5 n
dimes = (40-n) value = 10 (40 -n) summed = 285
5n + 10 (40-n) = 285 solve for n then d = 40 -n
Pythagorean theorem
14^2 = L^2 + L^2
196 = 2 L^2
98 = L^2
L = sqrt 98 SImplify further if needed .....
For this to occur either the 1st 2nd or 3rd must be a Wednesday
which would make Halloween (the 31 st) be a Friday Thursday or Wednesday respectively
