With the help of equations, we know that the value of equation 2(d1- d2) is 4.

<h3>What is an equation?</h3>
  • A mathematical expression with an equals sign is referred to as an equation.
  • Algebra is widely used in equations.
  • When performing calculations but unsure of the precise amount, algebra is used.
  • The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
  • For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

The equations we have are as follows:

  • d1 = a+2a+3
  • d2 = 2a+a+1

After simplifying, d1= 3a+3:

  • d2 = 3a+1
  • 2(d1-d2) = 2(3a+3-3a-1)
  • =2(2)
  • = 4

Therefore, with the help of equations, we know that the value of equation 2(d1- d2) is 4.

Answer:

(x - 9)(x + 3)

Step-by-step explanation:

Given

x² - 6x - 27

Consider the factors of the constant term (- 27) which sum to give the coefficient of the x- term (- 6)

The factors are - 9 and + 3, since

- 9 × 3 = - 27 and - 9 + 3 = - 6, thus

x² - 6x - 27 = (x - 9)(x + 3)

Pieces of Mail. The number of pieces of mail
Zina [86]

Answer:

20.8%

Step-by-step explanation:

The number of the pieces of mail handled by the U.S postal service decreased from 212,000,000,000 to 168,000,000

Therefore the percentage decrease can be calculated as follows

= 212,000,000,000-168,000,000,000

= 44,000,000,000/212,000,000,000 × 100

= 0.2075 × 100

= 20.8 %

Hence the percentage decrease is 20.8%
