I believe it’ll be 4/10 = 12/20

4/10=12/20

Because if you divide 12/20 by two you get 6/10 Nd it’s not equal to 4/10

In a histogram, are the lengths of the rectangles proportional to the width of the bars?​
Orlov [11]

Answer:

No

Step-by-step explanation:

In different scenarios, the data will be different. However, sometimes, it's impossible to draw a histogram with equal widths, so in order to maintain clarity and fairness, the area of the bars should actually be proportional to the frequency, which is usually the y-axis of the graph or height of the bars.

Hope this helps!

12 2/5 - 4 4/6 in whole numbers & fractions
Artist 52 [7]
12 2/5 - 4 4/6 = ?
Whole number: It cannot be a whole number, since it is a repeating decimal. As a repeating decimal, it is 7.7333333333333 and so on. If you round it to the ones place, it would become 8. As a simplified decimal, it would be 7.7

Fraction: 7 11/15

Which polynomial is factored completely
Ket [755]

Answer: The correct option is c.

Explanation:

Reason for correct option:

3x(9x^2+1)

This expression cannot be factored further because (9x^2+1) is the complete factor. Therefore the option c is correct.

Reason for incorrect option:

5x^2-17x+14=5x^2-10x-7x+14=5x(x-2)-7(x-2)=(x-2)(5x-7)

Since the given expression can be factored further therefore the option d is incorrect.

4(4x^4-1)=4((2x)^2-1)=4(2x^2-1)(2x^2+1)

Since the given expression can be factored further. Therefore the option a is incorrect.

2x(y^3-4y^2+5y)=2xy(y^2-4y+5)

Since the given expression can be factored further. Therefore the option b is incorrect.
