Answer:

9x^2 - 10x -4

Step-by-step explanation:

It is set up like this

     9x^2 - 8x

-              (x-2)2

First solve (x-2)2

the answer is (2x-4)

so now you can do this instead

    9x^2 - 8x

-              2x - 4

----------------------------------

9x^2 - 10x +4

9x^2 minus zero is 9x^2

-8x-2x is -10x

0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive

A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus

like this

    9x^2 - 8x

+              -2x + 4

----------------------------------

9x^2 - 10x +4

soldi70 [24.7K]

Answer:

<h2>x\leq -  \frac{8}{15}</h2>

Step-by-step explanation:

<h3>2x \leq -  \frac{2}{7} (8x + 8)</h3>

<u>First of all multiply through by 7</u>

We have

<h3>14x\leq - 2(8x + 8)</h3>

<u>Expand the terms in the bracket</u>

That's

<h3>14x\leq - 16x - 16</h3>

<u>Add 16x to both sides</u>

That's

<h3>14x + 16x\leq16x - 16x - 16 \\30x\leq - 16</h3>

<u>Divide both sides by 30</u>

We have the final answer as

<h3>x\leq -  \frac{8}{15}</h3>

Hope this helps you

Vera_Pavlovna [14]

Answer:

47 cm.

Step-by-step explanation:

Alex, Bruno, and Charles each add the lengths of two sides of the same triangle correctly.

They get  27 cm, 35 cm, and 32 cm, respectively. Find the perimeter of the triangle, in cm

find:

Find the perimeter of the triangle, in cm. What is the most efficient strategy you can find to solve this problem?

<u>solution:</u>

27, 35, and 32 are each the sum of a different pair of sides of the triangle

Then 27 + 35 + 32 is the sum of all three sides, each counted twice.

Thus, 27 + 35 + 32 = 94 is twice  the perimeter

therefore,

the perimeter of the triangle is 94/2 = 47 cm.
