That would be C, D, E and F.
Answer of Part A is 243 Lunches
Answer of Part B is 850.50$
The answer to this answer choice is A. (45x12)+75=c
The solution to the problem is as follows:
<span>Area=h×w
</span><span>1(1/2) = h × 2 (<span>1/4)
</span></span><span>⟹3/2 = h × <span>9/4
</span></span><span>h = 3/2 ÷ <span>9/4
</span></span><span>Therefore, the height will be 2/3 yards if we use all the blue paint.

I hope my answer has come to your help. Have a nice day ahead and may God bless you always!
Answer:
z = x^3 +1
Step-by-step explanation:
Noting the squared term, it makes sense to substitute for that term:
z = x^3 +1
gives ...
16z^2 -22z -3 = 0 . . . . the quadratic you want
_____
<em>Solutions derived from that substitution</em>
Factoring gives ...
16z^2 -24z +2z -3 = 0
8z(2z -3) +1(2z -3) = 0
(8z +1)(2z -3) = 0
z = -1/8 or 3/2
Then we can find x:
x^3 +1 = -1/8
x^3 = -9/8 . . . . . subtract 1
x = (-1/2)∛9 . . . . . one of the real solutions
__
x^3 +1 = 3/2
x^3 = 1/2 = 4/8 . . . . . . subtract 1
x = (1/2)∛4 . . . . . . the other real solution
The complex solutions will be the two complex cube roots of -9/8 and the two complex cube roots of 1/2.
