Answer:
= 486 in²
Step-by-step explanation:
Linear scale factor = Image distance/object distance
Therefore; Linear scale factor = OL'/OL
= 54/ 12
= 9/2
Area scale factor is equivalent to the square of linear scale factor
Thus;
Area scale factor = (9/2)²
= 81/4
Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle
Area of the smaller rectangle = 4 ×6 = 24 in²
Therefore;
Area of enlarged or larger pic = 81/4× 24
<u>= 486 in²</u>
The answer is 34, just plug the numbers in
Yes
7x6=42
8x6=48
Hope that helped :D
Answer:
B
Step-by-step explanation:
Get rid of all common factors.
36/4 = 9
x^9/x^7 = x^2
y^4/y^3 = y
