X^2-16 is a difference of squares of the form:
(a^2-b^2) which always factors to:
(a+b)(a-b), in this case we have:
(x+4)(x-4), we are told that width is (x+4) so the length is:
(x-4)
Answer:
B.
D.
× 
Step-by-step explanation:


0.00411522633
= 0.00411522633
×
= 0.00411522633
B is incorrect which means it is the answer
This is not true.


where is
is any integer. So suppose we pick some value of
other than these, say
. Then

Answer:
-12
Step-by-step explanation:
Since m1 = 10x + 4 and m2 = 5x - 4 then we can write it as:
10x+4=5x-4
Combine the like terms:
10x-5x=-4-4
5x=-8
Divide both sides by 5
5x= -8/5
x=-8/5
Now substitute the value of x in 5x-4
= 5(-8/5) - 4
= -8-4
= -12
Thus m2 = -12....
