Answer:
Area =
Step-by-step explanation:
Let the width of portrait be 'w'
Given:
Height of portrait without frame (h) = 1.5 times its width =
Width of the frame is 3 inches on all sides.
Area of the framed portrait is the total area of the portrait plus the area of the frame.
The figure representing the above scenario is shown below.
From the figure, area of rectangle ABCD is the area of the framed portrait.
From the figure,
AB =
BC =
Now, area of the rectangle ABCD is given as the product of the length AB and width BC. Therefore,
Therefore, the expression for the area of the framed portrait in terms of the width 'w' is given as:
Area =
4/10 and 10/25 are equivalent to 2/5.

Answer:
684.45
Step-by-step explanation:
Hey! Here's my explanation :)
You need to do 507 x 0.35
You would get 177.45
Then, you would need to add 507+177.45
You would get 684.45
The original price would be 684.45 :))
= a^3 +3a^2-7a+4a^2+12a-28
=a^3 +7a^2+5a-28
