Answer:
31.5 square inches
Step-by-step explanation:
First, you need to enlarge each side with a scale factor of 1.5.
7 inches = 10.5 inches
2 inches = 3 inches
The new sides are 10.5 and 3 inches long. Now, you need to use these side lengths in the area formula of a rectangle.
A = Bh
A = 10.5(3)
A = 31.5 in.²
Vertical stretch/compression is achieved by multiplying the function by a certain constant:
In particular, if the function is vertically stretched by a factor k, otherwise, if , the function is vertically compressed by a factor k.
So, in your case, you want to multiply the function by 1/4:
The answer is b
2/5 times 2/5 is equal to 4/25
these events don’t have relation so they are independent
