What is another way to write to 72- (-25) ?
Valentin [98]

Your answer would be 1, or 72+25.

What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.

Another way I like to think about this is the two minus symbols combine together to form a plus sign.

Hope this helped!

Calculate the density of the object using the information in the picture. Question 5 options: 0.052 ml/g 19.2 g/ml 19.2 ml/g 139
olga_2 [115]

The density of an object is obtained by taking the ratio of the mass of the object and its volume ; Density = \frac{Mass}{Volume}

There is no picture attached and no picture corresponding to the question could be found.

  • However, the required formular for calculating the density of an object is :

  • Density = \frac{Mass}{Volume}

  • The mass of the object is measured in gram(g) or kilogram(kg)

  • The volume of the object measured in Litre or any equivalent unit.

Therefore, the density of the object is the ratio of its mass and volume.

Solve the following quadratic equations
valentinak56 [21]

Answer:

see explanation

Step-by-step explanation:

To solve these equations equate them to zero, that is

x² - x - 42 = 0

Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)

The factors are - 7 and + 6, since

- 7 × 6 = - 42 and - 7 + 6 = - 1 , thus

(x - 7)(x + 6) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 6 = 0 ⇒ x = - 6

Solutions are x = - 6, x = 7

---------------------------------------------------------

x² + x - 6 = 0 ← in standard form

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

Solutions are x = - 3, x = 2

------------------------------------------------------------

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take the square root of both sides )

x = ± \sqrt{25} = ± 5

Solutions are x = - 5, x = 5
