GETS BRAINILIST!!!!What number should be placed in the box to help complete the division calculation? long division setup showin
Ilia_Sergeevich [38]

The unknown value is being subtracted from 702 is 650

Step-by-step explanation:

Long division setup showing an incomplete calculation

  • 13 is in the divisor
  • 3302 is in the dividend
  • 2 hundreds and 5 tens is written in the quotient
  • 2600 is subtracted from 3302 to give 702
  • An unknown value represented by a box is being subtracted from 702

We need to find this number

Lets write the steps above

∵ The dividend = 3302

∵ The divisor = 13

- 2 hundreds means 200 and 5 tens means 50

∵ The quotient = 200 + 50 + x

∵ Dividend = divisor × quotient

∴ (13 × 200) + (13 × 50) + (13 × x) = 3302

∵ 13 × 200 = 2600

- Subtract 2600 from the dividend

∴ 3302 - 2600 = 702

∵ 13 × 50 = 650

∴ 702 - 650 = 52 ⇒ 650 is the unknown value

∵ 13 × x = 13x

∵ 52 - 13x = 0

- Add 13 x to both sides

∴ 52 = 13x

- Divide both sides by 13

∴ x = 4

∴ 3302 ÷ 13 = 200 + 50 + 4

∴ 3302 ÷ 13 = 254

∴ From the steps above the missing number subtracted from

   702 is 650

The unknown value is being subtracted from 702 is 650

Add the following polynomials, then place the answer in the proper location on the grid.
aivan3 [116]

Answer:

x^3 - 6x + 2

Step-by-step explanation:

The given polynomials can be added together by adding like terms together as shown below:

=> Add together, the coefficient of all terms that have the power of 3.

(2x^3) + (x^3) + (-3x^3)

2x^3 + x^3 - 3x^3

3x^3 - 3x^3

x^3

=> (-4x^2) + (6x^2) + (2x^2)

-4x^2 + 8x^2

4x^2

=> (6x) + (-8x) + (-4x)

6x - 8x - 4x

-6x

=> (-3) + (12) +(-7)

-3 + 12 - 7

2

The answer = x^3 - 6x + 2
