The result of the evaluation as demanded in the task content is; -40 - 80√3.

<h3>What is the value of a²-b²?</h3>

The expression; a² - b² can be evaluated by means of difference of two squares as follows;

a² - b² = (a+b)(a-b)

Therefore, we have;

= ((√3 +5√3 -5) + (√3 -5√3 -5)) ((√3 +5√3 -5) - (√3 -5√3 -5))

= (2√3 -10)(10√3 +10)

= 60 - 80√3 -100

= -40 - 80√3.

Re-write the quadratic function below in Standard Form<br> y= –2(x + 5)(x – 4)
Naddik [55]

Answer:

y = - 2x² - 2x + 40

Step-by-step explanation:

Standard form of a quadratic is y = ax² + bx + c : a ≠ 0

Given

y = - 2(x + 5)(x - 4) ← expand factors using FOIL

  = - 2(x² - 4x + 5x - 20)

  = - 2(x² + x - 20) ← distribute parenthesis by - 2

  = - 2x² - 2x + 40 ← in standard form

The combined land area of the countries A and B is 178,973 square kilometers. Country A is larger by 373 square kilometers. Dete
ruslelena [56]
X=area of the country A
y=area of the country B
we saggest this system of equations:
x+y=178,973
x=y+373
we solve this system of equations by substitution method.
(y+373)+y=178,973
2y=178,973-373
2y=178600
y=178,600/2=89,300

x=y+373
x=89300+373=89,673

answer:
area of the country A=89,673 Km²
area of the country B=89,300 Km²

To check
The combined land area of the countries A and B is =89,673 Km²+89,300 Km²=178,973 Km²
Country A (89,673 Km²) is 373 Km² more larger than country B (89,300 Km²).
89,673 Km²=89,300 Km²+373 Km²
