Answer:

He is false

Step-by-step explanation:

Hey there!

The area of a shape is the total measurement of the inside of the shape

Meaning the parts I shaded in the screenshot

As you can see in the image, there is less area in shape B than shape A

Meaning, that the area has decreased

Now, Tom says that both area and perimeter has decreased

Lets check if the perimeter has decreased

If you look at it, the perimeter hasn't decreased at all

All that has happened was the shape getting a new form

The dimension are basically split

For example, if the top side of the square was 6 inches

Then the dimension after taking out a square from the shape would split

The top side of that square after is was split would be something along the ligns of 4 inches, and 2 inches and other dimensions like that

That is how I think of the perimeter and if it changes or not

But this explains why Tom is wrong

Since the perimeter is still the same

Tom is wrong

Answer:

1. (x+6)(2x - 3)(x - 1)²

2.(x-2)²(-2x - 1)²(-x + 1)

3. (-x + 1)³(x + 2)²(x - 3)

4. (-2x + 1)²(x - 3)²(x + 1)

Step-by-step explanation:

1. Degree 4, leading coefficient positive

(x+6)(2x - 3)(x - 1)²

That's the only equation with a degree of 4 (meaning x^4).

If you square the last parenthesis, you'll get an x^2, multiplied by the 2nd parenthesis you'll get an x^3 and multiply with the first parenthesis you'll get an x^4.

2. Degree is 5, leading coefficient is negative

(x-2)²(-2x - 1)²(-x + 1)

If you do the square of each of the first two parenthesis, you'll get something like (x²...)(4x²...)(-x + 1)

Multiply the first two parenthesis, to get (4x^4....)(-x + 1)

So, at the end you'll get -4x^5....

3. Degree 6, leading coefficient negative

(-x + 1)³(x + 2)²(x - 3)

That's the only equation of degree 6 given... so the choice is easy. Let's verify it's degree 6 and with negative leading coefficient.

Cube the first term and square the second one, you'll get something like...

(-x³...)(x²....)(x - 3)

If you combine all that you'll get something like -x^6....

4. Degree is 5, leading coefficient is positive

(-2x + 1)²(x - 3)²(x + 1)

If you do the square of each of the first two parenthesis, you'll get something like (4x²...)(x²...)(x + 1)

Multiply the first two parenthesis, to get (4x^4....)(x + 1)

So, at the end you'll get 4x^5....

For what values of k will the graph of y=kx+3 be a descending line?

Stells [14]

K is the slope
it is decending when the slope is negative

so for all values of k such that k<0, it will be decending

Write the sum using summation notation, assuming the suggested pattern continues. 1 - 3 + 9 - 27 + ...

meriva

There is no sum for this geometric series. it diverges rather than converges due to the absolute value of the common ratio (r), which is -3, being 3. for a geometric series to have a sum (to converge), the absolute value of r must be less than 1.
(you find r by dividing a2/a1, a3/a2, etc.)
hope this helps

PLEASE BELP ASAP Find the area of the shape below. 9 cm 11 cm 6 cm 15 cm

guapka [62]

Answer:

105 cm squared

Step-by-step explanation:

15×6 to get the rectangle =90

then we have a triangle left so you do 15- 9 for the base =6 and multiply that by hight (6×5=30) and since it's a triangle and not a square we have to divide that answer by 2 and we get 15. Add those together, we get 105. Hope that helped!
