Explanation :
So, here we are to factor the polynomial :
Some points to know :
- Factorisation is the reverse process of multiplucation.
- The Factorisation is the process of finding two or more expressions such that their product is the given expression
The area of the frame not covered by the painting is 192 square inches
<em><u>Solution:</u></em>
Given that, A rectangular painting is 24 inches wide and 20 inches tall without the frame
The area of rectangle is given as:
<em><u>Find the area of painting without frame:</u></em>
Length = 20 inches
Width = 24 inches
Thus area of painting without frame is 480 square inches
With the frame, it is 28 inches wide and 24 inches tall
<em><u>Find the area of painting with frame:</u></em>
Length = 24 inches
Width = 28 inches
Thus area of painting with frame is 672 square inches
<em><u>What is the area of the frame not covered by the painting</u></em>
Area of the frame not covered by the painting = Area with farme - Area without frame
Area of the frame not covered by the painting = 672 - 480 = 192
Thus the area of the frame not covered by the painting is 192 square inches
Answer:
Step-by-step explanation:
we know that
If two figures are similar, the the ratio of its corresponding sides is equal
In this problem we have
smaller cone
larger cone
