Answer:

Okay so for this one use the Pythagorean theorem

Step-by-step explanation:

A^2 + 28^2 = 128^2

You are trying to find A.

So 28^2 is 784

128^2 is 16384

Now you will subtract 784 from both sides of the equation your new equation should be this: a^2 = 15600

Now you find the square root of both sides which gives you: A= 124.89 round it to 125

Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending power

VikaD [51]

Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Step-by-step explanation:

Given expression is $(6x^2-4x+11)+(4-x^2-3x)$

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

$(6x^2-4x+11)+(4-x^2-3x)$

$=6x^2-4x+11+4-x^2-3x$

Adding the like terms we get

$=5x^2-7x+15$

$(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15$

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>
