Answer:

  C) In step 3, he should have determined which square is closest to 18.

Step-by-step explanation:

17.64 also rounds to 18. 17.64 differs from 18 by ...

  18 -17.64 = 0.36

whereas 18.49 differs from 18 by ...

  18.49 -18 = 0.49

Hence 17.64 is closer to 18 and we might expect 4.2 to be closer to √18 than is 4.3.

___

The actual root of 18 is about 4.243, so 4.2 is a better approximation.

fiasKO [112]

Answer:

The slope is m=-\frac{2}{9}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(-1,6)\ B(8,4)

Substitute the values

m=\frac{4-6}{8+1}

m=\frac{-2}{9}

m=-\frac{2}{9}

Rewrite, using the distributive<br> property.<br> 5(2x – 3y) = [?]* - [ ]y
olchik [2.2K]

Answer:

10x-15y

Step-by-step explanation:

So, when they say use the distrubutive property, they basically mean turning this:

a(b+c)

Into this:

ab+ac

So in this case, it would be:

5(2x-3y)

And we will turn it into:

10x-15y

ANother way to think about it is we are multiplying 2x by 5, and -3y by 5. So:

2x*5

=

10x

And

-3y*5

=

-15y

Then we can combine these two:

10x-15y

Hope this helps!

Write the answer in standard form.
viktelen [127]

Answer and step-by-step explanation:

We learn that (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

So in this case, it would be:

= x^3 + (3*x^2*2) + (3*x*2^2) + 2^3

= x^3 + 6x^2 + 3x * 4 + 8

= x^3 + 6x^2 + 12x + 8

This is the standard form of the equation

Hope it help you :3
