Well I THINK triangle ABC is just a stretched out version of triangle DEF.
To find the area of a triangle, you multiply base and height, and divide by 2.
Area of DEF is 6, so that means that (4 * x)/2 = 6.
6*2 = 12....
4 * x = 12........
4 * 3 = 12.
x = 3.
Comparing DEF to ABC: ABC's base is 3 times as long as DEF's. So that means the height must be three times as long.
3*3 = 9.
(12 * 9)/2 =54
Answer:
Step-by-step explanation:
The answer is 9 by the way. Draw a circle with sixty slices, shade in 15% or 9 slices.
Answer:
2x in common (slope)
Step-by-step explanation:
similar because they both have a slope of 2
different because the 2nd equation has a y intercept of 3
