Answer:
A is TRUE (44 in²*2=88 in²)
B is FALSE x(x-3)=88 (the rectangle) or x(x-3)/2=44 (the triangle)
C is TRUE if x(x-3)=88==>x²-3x-88=0
D is TRUE :
x²-3x-88=0
Δ=9+4*88=361=19²
==>x= 11 or x=-8 (excluded for <0)
E is FALSE for 11*4≠88

First you'd subtract .58 from 2.23 to get the price of the notebook.
2.23 - .58 = 1.65

Now subtract 6.11 from ten to figure out the change amount.
10 - 6.11 = 3.89
Answer:
6 i
Step-by-step explanation:
The imaginary number "6 i" when squared gives :
With replacement, probability of selecting a good bulb remains
(63-9)/63
=6/7
If the bulbs are selected WITH replacement three times, then
P(all good)
= (6/7)^3 (by the multiplication rule)
= 216/343
= 0.630 (to three decimal places)
