area = product of adjacent sides
so area = (4x + 5)(3x + 10)
can you expand this?

= 4(3x + 10) + 5(3x + 10)
can you continue?

r u there?

Sorry yes.

I am confused.

do you follow why
(4x + 5)(3x + 10) is the expression for the area of the rectangle?

A little....

Ok okay :]

placing them together means they are to be multiplied

O okay :]

(4x + 5)(3x + 10)
now we have to first multiply (3x + 10) by 4x then by 5
= 4x(3x + 10) + 5(3x + 10)

ok?

Okay

can you do that?

yes 1 min :]

12x2+55x+50?

yes right
that represents the are of the rectangle

Part B the degree of the expression is the highest power which is in 12x^2
so its degree 2

So that answer is for part a?
12x^2+55x+50?

yes

OKay :]

ant its an example of a polynomial In fact as it has 3 terms so its a trinomial
thats part B

The last two comments you said correct?

First its degree 2 and its classified as a trinomial.

thats answer to part B

OK THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!

What part C lol.

Thats all for part c?

yes

Can you help me with 1 more?

one polynomial multiplied another polynomial gives another polynomial

sorry i gotta go right now

Oh ok :-/
