<h3><u>Answer:</u></h3>

Hence, the simplified expression is:

40w^2+41w+10

<h3><u>Step-by-step explanation:</u></h3>

We have to simplify using a table to simplify the term:

(5w+2)(8w+5)

i.e. this is evaluated as:

5w 2

8w 40w^2 16w

5 25w 10

The value in the table are obtained by multiplying each of the row entry with the corresponding column entry and hence the final result is the addition of all the entries.

Hence we obtain a expression as:

(5w+2)(8w+5)=40w^2+16w+25w+10

=40w^2+41w+10

Hence, the expression is:

40w^2+41w+10

Answer:

y-intercept: (0, 5); slope: 1/4

Step-by-step explanation:

The slope (m) is found from ...

m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, this is ...

m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C

Then, the point-slope form of the equation of the line can be written as ...

y -y1 = m(x -x1)

y -6 = (1/4)(x -4) . . . fill in known values

y = 1/4x -1 +6 . . . . . add 6

y = 1/4x +5

Then the value of y when x=0 is ...

y = 0 +5 = 5

So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.

After talking with you here are two different options I think you are trying to ask:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about: $(\frac{-12}{3}) ^{3}$

Answer: -62

Explanation:

PEMDAS tells us we need to do the exponent first:

-12³ = (-12)³ = -1728

<em>The parentheses are important so you cube the negative sign as well!</em>

3³ = 27

-1728 / 27 = -62

$(\frac{-12}{3}) ^{3}$ simplified is -62

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are talking about (-1 $\frac{2}{3}$ )³

Answer: - $\frac{125}{27}$

Explanation:

First, let us turn -1 and two thirds into a mixed number:

Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get $-\frac{5}{3}$

To cube it we must do:

( $-\frac{5}{3}$ )( $-\frac{5}{3}$ )( $-\frac{5}{3}$ )

3 times 3 (9) times 3 is 27

5 times 5 (25) times 5 is 125

So we have 125/27

For the negative, we have three - - -

Two cancel each other out, and we are left with one (-) so our answer is negative

(-1 $\frac{2}{3}$ )³ simplifed is - $\frac{125}{27}$

Marcus drew a line from point Y to point W in the rectangle shown below. He created two identical triangles. Classfy the triangl

VikaD [51]

The triangles that would be created if the rectangle has a length and width that are different is a right scalene triangle.

It will have one right angle and all three sides of the triangle will be different lengths because the hypotenuse (the diagonal will be longer than the other two sides.
