Question

Yup, I have NO CLUE where to start. WILL MEDAL AND FAN!

A large rectangle has a length of 2 inches and a width of 0.18 inches. A smaller rectangle has a length of x³ inches and a width of 0.49x³ inches.

a) What is the area of the large rectangle?
b) What is the area of the small rectangle?
c) Write a polynomial expression that represents how much greater the area of the larger rectangle is than the area of the smaller rectangle.
d) Rewrite this expression as a difference of squares

Answer 1

well you must be able to complet (a)

for (b) its \[A = x^3 \times 0.49x^3 \]

which you should be able to answer

Answer 2

Yeah I got that part

0.49x^6y=0.36

is the answer to C, how do I figure out D?

Answer 3

(c) the difference

\[P(x) = 0.49x^6 - 0.36\]

(d) \[P(x) = (0.7x^3 - 0.6)(0.7x^3 + 0.6)\]
