Answer:
Area = 1/2 Base x height
Step-by-step explanation:
To find the area of a triangle, multiply the base of the height and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into two triangles.
Answer:
y=2x-A
Step-by-step explanation:
Find the greatest common factor (GCF) of 9 and 12 using factor trees. The GCF is 3
Divide each term (9 and 12) over 3
9/3 = 3
12/3 = 4
So 9/12 reduces to 3/4
In other words, 9/12 = 3/4
--------------------------------------
Now focusing on 3/4, we can multiply top and bottom by the same value. Let's say we multiply top and bottom by 5
3*5 = 15
4*5 = 20
So 3/4 = 15/20
--------------------------------------
So two ratios equivalent to 9/12 are 3/4 and 15/20. There are infinitely other ratios that are equivalent.
In short, the answers are 3/4 and 15/20.
