It's not the difference of squares, rather it is the square of a difference. That leaves a perfect square trinomial, which narrows your selection to two choices. An expression with 2 terms is not a trinomial, so that further narrows your selection. The appropriate choice is
... (4xy -3z)² = 16x²y² -24xyz +9z², a perfect square trinomial
_____
The expression you have in your problem statement has no z term, so none of the choices is applicable to that one.
Answer:
2nd option
Step-by-step explanation:
The zeros are the points on the x- axis where the graph crosses.
Since the graph crosses the x- axis at x = - 1 and x = 5, then
The zeros are x = - 1 and x = 5
Answer:
The Probability of not getting two consecutive reds is 0.9506
Step-by-step explanation:
Number of sections = 9
Number of red sections = 2
Number of blue sections = 3
Number of green sections = 4
Probability of getting two consecutive reds = 
So,The Probability of not getting two consecutive reds =
Hence The Probability of not getting two consecutive reds is 0.9506
So since they are similar
AC/BC=CD/CE
so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units
