1 answer:

8 0

Rational numbers are numbers that can be turned into a fraction. They can be negative or positive.
Integers are whole numbers. They can be negative or positive.

Numbers such as 0.10 are rational because they can be turned into a fraction
0.10 = 1/10....and since it is not a whole number, it is not an integer.

Answer:

(i) 17 $\sqrt{2}$

(ii) 9 $\sqrt{6}$

(iii) 0

Step-by-step explanation:

(i) 7 $\sqrt{2}$ + 5 $\sqrt{2}$ $\sqrt{4}$ = 7 $\sqrt{2}$ + 10 $\sqrt{2}$ = 17 $\sqrt{2}$

(ii) 15 $\sqrt{6}$ - $\sqrt{216}$ = 15 $\sqrt{6}$ - $\sqrt{36}$ · $\sqrt{6}$ = 9 $\sqrt{6}$

(iii) 8 $\sqrt{45}$ - 8 $\sqrt{20}$ + $\sqrt{245}$ - 3 $\sqrt{125}$ = 8 $\sqrt{9}$ · $\sqrt{5}$ - 8 $\sqrt{4}$ · $\sqrt{5}$ + $\sqrt{49}$ · $\sqrt{5}$ - 3 $\sqrt{25}$ · $\sqrt{5}$ =

24 $\sqrt{5}$ - 16 $\sqrt{5}$ + 7 $\sqrt{5}$ - 15 $\sqrt{5}$ = 8 $\sqrt{5}$ - 8 $\sqrt{5}$ = 0

F(x) = x^2 - 16 and g(x) = x+4. Find f/g and its domain

Lunna [17]

$f(x)=x^2-16\\\\g(x)=x+4\\\\\dfrac{f}{g}(x)=\dfrac{x^2-16}{x+4}\\\\The\ domain:\ x+4\neq0\to x\neq-4\\\\\dfrac{f}{g}(x)=\dfrac{(x-4)(x+4)}{x+4}=x-4$

$Used:\ a^2-b^2=(a-b)(a+b)$
