Answer:

17 1/2

Step-by-step explanation:

8 5/8+8 7/8=...

So, let's take away the fractions for now.

What's 8+8?

Well, 8+8=16.

Now, let's take a look at the fractions.

5/8+7/8=...

Well, when we are adding fractions, the denominator will stay the same. So let's pretend that we are adding 5+7.

5+7= 12. So our answer is 16 12/8 Right?

wrong.

you will simplify the 12/8. Since the numerator is more than eight, we will subtract 8 from 12.

12-8=4

we will make the 8/8 a 1 and add it to the 16 to make it 17 4/8. We can still simplify this. The 4/8 becomes 1/2 making the answer: 17 1/2

The length of one of the sides of a square was increased by 4 dm, and the other one was decreased by 6 dm. As a result, a rectan

Inga [223]

Answer:

The answer to your question is 10 dm

Step-by-step explanation:

Data

length of a rectangle = x + 4

height of a rectangle = x - 6

Area of the rectangle = 56 dm²

length of the square = x

Process

1.- Find x with the information given for the rectangle

Area = length x height

Substitution

56 = (x + 4)(x - 6)

Expand

56 = x² - 2x - 24

Equal to zero

x² - 2x - 24 - 56 = 0

Simplify

x² - 2x - 80 = 0

Factor

(x - 10)(x + 8) = 0

Equal to zero

x₁ -10 = 0 x₂ + 8 = 0

x₁ = 10 x₂ = -8

2.- Conclusion

The length of the square is 10 dm because there are no negative lengths.
