The expression A² – (B + C) in its simplest form is 8x² – 25x + 7

<h3>What is the polynomial?</h3>

A polynomial function is an expression constructed with one or more terms of variables with constant exponents.

Data obtained from the question

A = 3x – 4, B = x + 7, C = x² + 2, A² – (B + C) =?

The simplest form of the polynomial is given by;

(3x – 4)² – (x + 7 + x² + 2)

9x² – 12x – 12x + 16 – (x + x² + 9)

9x² – 24x + 16 – x – x² – 9

9x² – x² – 24x – x + 16 – 9

8x² – 25x + 7

Hence, the simplest form of the polynomial is A² – (B + C) = 8x² – 25x + 7.

Find the value of x

Fiesta28 [93]

Answer:

x=26

Step-by-step explanation:

The sum of all angles in a triangle is equal to 180

x + 55 + (4x-5) = 180

Combine like terms

5x +50 = 180

Subtract 50 from each side

5x +50-50 = 180-50

5x = 130

Divide each side by 5

5x/5 =130/5

x =26

The mass of Venus is 4.87 × 10 24 kg. The mass of Earth is 5.97 × 10 24 kg. What is the difference in mass between these two pla

Aliun [14]

Answer: 1.1 x $10^{24}$ kg

Step-by-step explanation:

Mass of Venus = 4.87 x $10^{24}$

Mass 0f Earth = 5.97 x $10^{24}$

The difference in mass implies :

5.97 x $10^{24}$ - 4.87 x $10^{24}$

= 1.1 x $10^{24}$
