Given that t<span>here
are 20 light bulbs in 5 packages.
The table to find the rate
that gives you the number of light bulbs in 3 packages is given as follows:
![\begin{tabular}
{|c|c|c|c|c|c|}
Light bulbs&4&8&12&16&20\\[1ex]
Packages&1&2&3&4&5
\end{tabular}](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%0A%7B%7Cc%7Cc%7Cc%7Cc%7Cc%7Cc%7C%7D%0ALight%20bulbs%264%268%2612%2616%2620%5C%5C%5B1ex%5D%0APackages%261%262%263%264%265%0A%5Cend%7Btabular%7D)
Three different ways in which the rate can be written are:
12 light bulbs to 3 packages
12 light bulbs : 3 packages
12 light bulbs / 3 packages

Factor : x^2+3x-10
Answer = (x - 2)(x + 5)
Explanation:
Y = x^2 + 3x - 10.
Find 2 numbers knowing sum (3) and product (-10).
Factor pairs of (-10) -> (-1, 10)(-2, 5). This sum is 3 = b. The 2 numbers are: -2 and 5.
y = (x - 2)(x + 5).
 
        
                    
             
        
        
        
Answer:  A) ΔABD ≡ ΔECD
<u>Step-by-step explanation:</u>
Match up the letters of the congruent sides.
AD = ED      and    BD = CD
A D                        B D           →     ABD
E D                        C D           →     ECD
This can be written in any order as long as the letters are matched properly.   A & E,   D & D,   B & C
ADB          or        BDA       or     ...
EDC                      CDE
The only correct option provided is option A.
