Answer:

  4x   +5    \frac{-13}{x+5}

Step-by-step explanation:

x + 5 | 4x^2 + 25x + 12

        - <u>4x^2 + 20x</u>

                         5x + 12

                         <u>5x + 25</u>

Answer:

The quotient is 4x+5  and  the remainder is -13

Step-by-step explanation:

Using synthetic division

-5        4      25   12

Bringing down the 4 and multiplying

-5        4      25   12

        ↓       -20 -25

    ----------------------

         4        5    -13

The quotient is 4x+5  and  the remainder is -13

The total units of stationery he has would be 55 approximately.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

David keeps a range of stationery in his study.

Let the pencil is represented by x.

Let the erasers be represented by y.

Let the pens be represented by z.

Let n be the stationery.

5/7 of his stationery consists of pencils.

x = 5/7 n

1/6 of the remaining stationery consists of erasers.

y = 1/6 n

There are 20 pens in his study.

z = 20

The total stationery

X + y + z

5/7 n + 1/6 n + 20 = n

20 = n -23/ 36 n

20 = 13 / 36 n

n = 55.38

Therefore, the total units of stationery he has would be 55 approximately.

Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of squ
denis23 [38]

Answer:

The side of square A is 30 cm.

Step-by-step explanation:

Given that,

The dimensions of square A are three times the dimensions of square B.

The area of square A is 900 sq cm.

Side of square A = 3( side of square B)

Let the side of square B is b. So,

Side of square A, a = 3b

We know that, the area of square is side². So,

(3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm

Side of square A, a = 3(10) = 30 cm

Hence, the side of square A is 30 cm.

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
