Complete question is attached.
Answer:
a) ED = 6.5 cm
b) BE = 14.4 cm
Step-by-step explanation:
From the triangle, we are given the following dimensions:
AB = 20 cm
BC = 5 cm
CD = 18 cm
AE = 26 cm
We are asked to find length of sides ED and BE.
a) Find length of ED.
From the triangle Let's use the equation:
Cross multiplying, we have:
AB * ED = AE * BC
From this equation, let's make ED subject of the formula.
Let's substitute figures,
Therefore, length of ED is 6.5 cm.
b) To find length of BE, let's use the equation:
Cross multiplying, we have:
AB * CD = AC * BE
Let's make BE subject of the formula,

From the triangle, length AC = AB + BC.
AC = 20 + 5 = 25
Substituting figures, we have:


Therefore, length Of BE is 14.4cm
Answer:
1.28 ÷ 4 = 0.32
But the "models" make little or no sense. I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times. It also shows no reference to the decimal place, so I would say there is no real representation of it all.
8/5 is rational. It is expressed as a ratio of two integers.
√4 = 2 = 2/1 . This is rational because it expressed as ratio of two integers.
√64 = 8. This is rational because it expressed as ratio of two integers.
√10 = 3.16227..... The decimal part does not end and it is irrational because it can not be expressed as ratio of two integers.
Therefore √10 is irrational.
The x which achieve these statement is x=0.
