klemol [59]3 years ago

Answer:

(3)

Step-by-step explanation:

5x^2 - (2x-3)^2

5x^2- (2x-3)(2x-3)

now you distribute, the 5x^2 stay the same for now

So for now just (2x-3)(2x-3)

first 2x * 2x= 4x^2

2x * -3= -6x

-3 * 2x= -6x

-3 * -3= 9

So (2x-3)(2x-3) is 4x^2 -6x-6x+9

You can simplify that to 4x^2 -12x +9

Now we add in the 5x^2 from the start don't forget!

And we are subtracting sooo

5x^2 -(4x^2 -12x +9)

5x^2 -4x^2 +12x -9

x^2 +12x -9

Claire Drew model of 5/10 explain how Claire could change her model to show how many hundreds are in 5/10 I know this is like my
natta225 [31]

Answer:

There are 0.005 hundreds in 5/10.

Step-by-step explanation:

Claire drew model of 5/10

We want to know how many hundreds are in 5/10.

Let us use an obvious example.

There are three 2's in 6 right?

Suppose we didn't know this, and we are told to find how many 2's are in 6, we get this by representing this in an algebraic expression as:

There are x 2's in 6. This can be written as

2x = 6

Solving for x, by dividing both sides by 2, we have the number of 2's that are in 6.

x = 6/2 = 3.

Now, to our work

We want to find how many hundreds are in 5/10. We solve the equation

100x = 5/10

x = 5/1000 = 0.005

There are 0.005 hundreds in 5/10.
