The corrects answers are B and D for this one.
Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar.
For example;
Answer B.
50 / 10 = 5
and
30 / 6 = 5
Answer D.
7.5 / 2.5 = 3
and
4.5 / 1.5 = 3
Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles.
Hope this helps!

Find the y-intercept:
1 = 1/2(0) + b
1 = 0 + b
-0 -0
1 = b
The slope-intercept equation is:
y = 1/2x + 1
so its D
Answer:
Step-by-step explanation:
Givens
Let the number in the Spanish Class = x
Then the number in the Geometry Class = (4/5) x
Equation
x + (4/5)x < 54
Solution
x + (4/5)x < 54
4/5 = 0.8
x + 0.8x < 54
1.8x < 54 Divide both sides by 1.8
1.8x / 1.8 < 54/1.8
x < 30
The sign used in the equation is less than, not less than or equal to.
The number of students taking Spanish cannot equal 30. There must be 29 in the Spanish Class.
