26) Answer is choice A: y = -3
This is the horizontal line that cuts the figure into two congruent pieces.
--------------------------------------------------------------
27) Answer is choice A: AB = 24 and DE = 12
CA/DF = 12/6 = 2
CB/FE = 20/10 = 2
The ratio of the larger to smaller corresponding sides is 2:1 or just 2
So AB needs to be twice as long as DE
That only happens with choice A
Answer:
a. The possible dimensions of the total area are;
The width of the total area is (2·x + 8) inches
The length of the total area is (2·x + 10) inches
b. The dimensions of the photos are as follows;
The length of the photos are 10 inches
The width of the photos are 8 inches
Step-by-step explanation:
a. Given that the area, A = 4·x² + 36·x + 80
We get;
A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)
Therefore, the possible dimensions of the total area (photo + mat) are;
The width of the total area (photo + mat) = (2·x + 8) in.
The length of the total area (photo + mat) = (2·x + 10) in.
b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each
Therefore, we have the dimensions of the photos are as follows;
The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.
The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.
13.08x12 =156.96. All you have to do is multiply
Hello there, and thank you for posting your question here on brainly.
Short answer: C. 9
Why?
Box and whisker plots are confusing, the line in the middle is the median, but we don't need to do that now. The dots on the lines outside of the box show the largest and the shortest number. The plotted point on the way left is your answer, the line plotted is 9.

L - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30
So Lane has 3 years old and Mel has 30 years old.
