<span>a. 72 And 115
7+2=9
1+1+5=7
not true that both are divisible by 3
b. 120 And 835
1+2=3
8+3+5=16</span>
<span><span>not true that both are divisible by 3
but, they're both divisible by 5! (0 or 5 at the end)
not relatively prime
</span> c. 201 And 735
2+1=3
7+3+5=15
both are divisible by 3!
d. 303 And 1041
3+3=6
1+4+1=6
both divisible by 3
so the answer is a </span>
A: Foil
(b+2)(b+2)=b²+2b+2b+4=b²+4b+4
B: Again, Foil
(x+3)(x-3)=x²+3x-3x-9=x²-9
let
x-------> the number of Lucy's orders
y-------> the number of Sam's orders
z-------> the number of Bob's orders
we know that
<u></u>----> equation A
-----> equation B
-----> equation C
substitute equation B and C in equation A
find z
find y
therefore
<u>the answer is</u>
the number of Lucy's orders is
the number of Sam's orders is
the number of Bob's orders is
Answer:
Step-by-step explanation:
The orange divisor(s) above are the prime factors of the number 168. If we put all of it together we have the factors 2 x 2 x 2 x 3 x 7 = 168. It can also be written in exponential form as 23 x 31 x 71
