In △abc point d is the midpoint of ab , point e is the midpoint of bc , and point f is the midpoint of be . find area of △abc, if adcf= 63 cm2.

168

Step-by-step explanation:

Consider triangles CDF and FDB. In these triangles the heights drawn to the sides CF and FB are the same. Then

Then

Consider triangle BCD. The area of this triangle is

Consider triangle ABC, the area of triangle ABC is

168 cm².

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
