Answer:
Maximum is 4
Step-by-step explanation:
M(x) is quadratic function, so we need to fin maximum.
m(x)=-x(x-4)
m(x)=-x^2+4x
To find a maximum we need to find m’
M’(x)=-2x+4
M’(x)=0 if x=2
The maximum is in the point x=2
M(2)=-2(2-4)=4

- Enlargement
- The new larger rectangle is 16.8 inches by 8.4 inches
==============================================================
Explanation:
I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.
The scale factor being larger than 1 means we have an enlargement.
The image is going to be larger compared to the preimage.
The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4
The image rectangle is 16.8 inches by 8.4 inches
