<u>Answer:</u>

$\sf 9x^2 - 12x^5 +6x$

<u>solving steps:</u>

$\hookrightarrow \sf (3x^2 + 6x^2 + 9x )- (4x^5 + 8x^5 + 3x)$

remove parenthesis

$\hookrightarrow \sf 3x^2 + 6x^2 + 9x - 4x^5 - 8x^5 - 3x$

group variables

$\hookrightarrow \sf 3x^2 + 6x^2 - 4x^5 - 8x^5 - 3x+ 9x$

simplify

$\hookrightarrow \sf 9x^2 - 12x^5 +6x$

Answer:

$12x^5-9x^2-6x$

Step-by-step explanation:

$\left(4x^5+8x^5+3x\right)-\left(3x^2+6x^2+9x\right)$

$4x^5+8x^5+3x-\left(3x^2+6x^2+9x\right)$

$(4x^5+8x^5):12x^5$ ( Combine like terms)

$12x^5+3x-\left(3x^2+6x^2+9x\right)$ (Apply the distributive law)

$12x^5+3x-9x^2-9x$

$(3x-9x):-6x$ ( Combine like terms)

$12x^5-9x^2-6x$

r-ruslan [8.4K]

Answer:

$Total = 7\frac{1}{2} cups$

Step-by-step explanation:

Given

Initially, he drank 3 pints of water

Then, $1\frac{1}{2}$ more cups

Required

How many cups did Ian drink altogether

This question can be solved by adding the size of water he drank during the hike and when he got home

i.e.

$Total = 3\ pints + 1\frac{1}{2} cups$

But the answer should be in cups;

So, number of pints has to be converted to number cups

Given that 1 pint = 2 cups;

3 pints will be 3 * 2 cups

3 pints = 6 cups;

So,

$Total = 3\ pints + 1\frac{1}{2} cups$

$Total = 6\ cups + 1\frac{1}{2} cups$

$Total = 7\frac{1}{2} cups$

Altogether, he drank $7\frac{1}{2} cups$ of water

<h3>Explanation:</h3>

The first attachment is one way that quadrilaterals can be classified. If you've never studied a diagram like this before, it would certainly be mysterious.

There is a little more to it in that a "kite" is not the only kind of quadrilateral with no parallel sides.

Your diagram apparently doesn't recognize the special sorts of trapezoids you might have other than isosceles.

___

The classifications on the first diagram are numbered. The numbers on the second diagram are the way I'd match up the descriptions to the bubbles in your diagram.
