Answer/Step-by-step explanation:

Let's use Pythagorean theorem:

Formula : a² + b² = c²

Note that:

a is the long leg of the triangle

b is the short leg of the triangle

c is the hypotenuse

Side lengths Given are; 3 inches, 4 inches, 5 inches of a right triangle.

Hence,

a = 4 inches

b = 3 inches

c = 5 inches

Thus,

4² + 3² = 5²

16 + 9 = 25

25 = 25  [True]

What are the solutions of 2x^2+3x-7=x^2+5x+39
sveticcg [70]

Answer:

{x}^{2}  - 2x - 46

Step-by-step explanation:

{2x}^{2}  + 3x -  7 =  {x}^{2}  + 5x + 39

Collect like terms

{2x }^{2}  -  {x}^{2}  + 3x  - 5x - 7 - 39

{ x}^{2}  - 2x - 46

F(x)= 9x + 2 over 3X^2+5x-12
Maurinko [17]
Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)

Factor the denominator to find the excluded values of x...

3x^2+5x-12

3x^2+9x-4x-12

3x(x+3)-4(x+3)

(3x-4)(x+3)

So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:

x=(-oo, -3),(-3, 4/3),(4/3, +oo)

Is ∞ an abstract term or a real number? And are there any numbers larger than ∞?
Yanka [14]
A number is defined as an arimethical value, expressed by word or symbol. by definition infinity is NOT a "number" as it holds no "actual" value.

infinity can not be represented so it is above digits. infinity squared would be uncountable thus infinity, therefore, there is no number higher than infinity.
