Answer: 17x^2 + 11x + 16

Step-by-step explanation:

The first term is,  17x^2  its coefficient is  17 .

The middle term is,  +11x  its coefficient is  11 .

The last term, "the constant", is  +16  

Step-1 : Multiply the coefficient of the first term by the constant   17 • 16 = 272  

Step-2 : Find two factors of  272  whose sum equals the coefficient of the middle term, which is   11 .

     -272    +    -1    =    -273  

     -136    +    -2    =    -138  

     -68    +    -4    =    -72  

     -34    +    -8    =    -42  

     -17    +    -16    =    -33  

     -16    +    -17    =    -33

If 3 employees took 3/4 of a pie Home how much pie did wacho employee receive
Aleksandr [31]

Answer:

2 1/4 pies or 2.25

Step-by-step explanation:

3/4 = .75 = 75%

a whole pie is 100% or 1

3 took 3/4

so

3 x .75 = 2.25

lets break this answer down

if 1 is a whole pie then that would mean 2 would equal 2 whole pies

now with the left over .25 it would be 25% so 2 1/4

What is the value of x in the equation is 4+6x=-3+7x​
Anvisha [2.4K]

Answer:

x=1

Step-by-step explanation:

  1. choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
  2. so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
  3. so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
  4. then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
  5. but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
  6. then divide by 7 to get x by itself so it will look like this 7=x
  7. but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x

and thats all there is to it hope this helps
