AB = 9 cm
BC = 6cm
CD = 7 cm
AE = 6 cm
3BC = AB
3ED = AE
AB = AE
BC ED
⁹/₃ = ⁶/ₓ
3 · 6 = 9 · x
18 = 9x
9 9
2 = x
ED = 2 cm
The answer is a is greater than or equal to 13 :)
Answer:
29.9 cm
Step-by-step explanation:
First things first. 7/8 x 4/5 is 28/40=7/10. It is smaller than both numbers. When multiplying fractions, the answer gets smaller and smaller. The answer of multiplying fractions will always be smaller than both factors because you are multiplying a number less than 1 so it just gets smaller and smaller. That’s the best I can explain it. Sorry:)
