Rewrite as a simplified fraction.
2.31 with the 1 repeating

Step-by-step explanation:

Let x be equal to that.

Multiply by 1 followed by as many zeros as repeating numbers. In this case it's just one repeating decimal, therefore, 1 followed by 1 zero or 10.

This basically moves the decimal point one number to the right.

Subtract the first equation from this new equation.

--------------------------

The repeating decimal is eliminated and we are left with:

23.1

- 2.3

---------

20.8

We also have 10 - 1 = 9. We are left with:

Divide by 9.

To get rid of the decimal, multiply by 1 followed by as many zeros as decimals. In this case 1.

Let's simplify.

208/2=104

90/2=45

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
