$\dfrac{4}{10} + \dfrac{28}{100} = \dfrac{4 \times 10 }{10 \times 10} + \dfrac{28}{100} = \dfrac{40}{100} + \dfrac{28}{100} = \dfrac{40+28}{100} = \dfrac{68}{100} =\dfrac{68 \div 4}{100 \div 4}= \dfrac{17}{25}$

Hi there!

4/10 = (4*10)/(10*10) = 40/100

40/100 + 28/100 = 68/100

68/100 = 34/50 = 17/25

Hope this helps!

Draw a rectangle & inscribe inside this rectangle 2 circles that do not intersect.

cercle₁ ∩ cercle₂ =Ф.
Their complement would be the part of the rectangle - the 2 circles

Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?

Fudgin [204]

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

$||x-4||$ , we get
