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:
1.78 x 10^8
Step-by-step explanation:
178000000
I usually count the number of zeros first so in this case, it would be 6
178 x 10^6
This wouldn't be standard form because the number should be between 1 and 9
178 ÷ 100 = 1.78
I divided this number by 100 so I would times 10^6 by a 100
10^6 x 100 = 10^8
the answer would be 1.78 x 10^8
i hope this helps!
