Answer:
20
Step-by-step explanation:
The first step is to find out the similarity reason of the sides of the triangle, so we just divide the big side by the small side (12/4=3).
Now, for the similarity reason of the areas, we just square that number (3^2=9).
Then we just divide the area of the big triangle by 9, which is 180/9= 20.
Step-by-step explanation:
(6r + 7)+(13 + 7r)
= 6r + 7 + 13 + 7r
= 6r + 7r + 13 +7
= 13r + 20
There both the same score. she has the same score on each test. i hope this helps:)
