Answer:
Try 116?
Explanation:
First, let's us know the formula for finding area of a rectangle.
Formula - A = l * w
In the image, it shows the length (12) and width (10)
Length = L
Width = W
Now, what is 12 x 10? 120
Because we need the shaded region and the little box isn't apart of it, we need to find the area of that box to and subtract it from big box
The length is 2 and the width is 2, shown by the image.
2x2 = 4
120-4 = 116
That has to be impossible because you can’t get any solution that would possible add to 6
Given:
The triangles DEF is similar to GHF.
The objective is to find a similar ratio of DF/DE.
Explanation:
Using the basic proportionality theorem, for the similar triangles DEF and GHF,

Considering the first two ratios of equation (1),

On interchanging the segments further,

Hence, the required segment in the blanks is GF/GH.
Hello from MrBillDoesMath!
Answer:
The second choice, [1,2]
Discussion:
The key to this question is that we are looking for "local maximum". In the graph a local maximum, think "camel hump", occurs in the interval [1,2] -- but the global maximums, if there is one, appears to occur in x > 3 and x < -1
Thank you,
