Answer:

-2x-7y

Step-by-step explanation:

We have the expression -(4x+y)+2(x-3y) and we have to simplify it:

<em>Observation: -(4x+y)=(-1)(4x+y)</em>

We have to use distributive property this is: a(x+y)=ax+ay

Then,

(-1)(4x+y)+2(x-3y)=\\(-1).4x+(-1).y+(2).x+(2).(-3y)=\\=-4x-y+2x-6y

Ordering:

-4x-y+2x-6y=\\-4x+2x-y-6y=\\=-2x-7y

Then the simplest form of  -(4x+y)+2(x-3y) is -2x-7y

Answer:

- 2x - 7y

Step-by-step explanation:

Given

- (4x + y) + 2(x - 3y)

Distribute both parenthesis, noting that the first is distributed by - 1

= - 4x - y + 2x - 6y ← collect like terms

= (- 4x + 2x) + (- y - 6y )

= - 2x + (- 7y) = - 2x - 7y

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more t
valentina_108 [34]
The answer is  0 < x <span>≤ 7 
</span>
First, we know that width =  x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18)  ≤ 175

X^2 + 18x - 175  <span>≤ </span>0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 <span>≤ 175 + 81

(x + 9)^2 </span><span>≤ 256

|x + 9| </span><span>≤ sqrt(256)

|x + 9| </span><span>≤ +-16

-16 </span>≤ x + 9 <span>≤ 16

</span>-16 - 9 ≤ x <span>≤ 16 - 9

</span>-25 ≤ x <span>≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
</span> 0 < x ≤ 7
