Answer:

$5(3w+13)$

Step-by-step explanation:

1) Prime factorization of 65 and 15 will give us 5 as is Greatest Common Factor

65|5

13|13

15|5

3|3

2) Placing the common factor outside the parentheses. And inside the sum of its quotients.

$\frac{65}{5}=13\\\frac{15w}{5}=3w\\$

There you have, a simplified expression:

$5(3w+13)$

Answer:

OPTION C: Sin C - Cos C = s - r

Step-by-step explanation:

ABC is a right angled triangle. ∠A = 90°, from the figure.

Therefore, BC = hypotenuse, say h

Now, we find the length of AB and AC.

We know that: $\textbf{Sin A} = \frac{\textbf{opp}}{\textbf{hyp}}$

and $\textbf{Cos A} = \frac{\textbf{adj}}{\textbf{hyp}}$

Given, Sin B = r and Cos B = s

⇒ $Sin B = r = \frac{opp}{hyp} = \frac{AC}{BC} = \frac{AC}{h}$

⇒ $\textbf{AC} = \textbf{rh}$

Hence, the length of the side AC = rh

Now, to compute the length of AB, we use Cos B.

$Cos B = s = \frac{adj}{hyp} = \frac{AB}{BC} = \frac{AB}{h}$

⇒ $\textbf{AB} = \textbf{sh}$

Hence, the length of the side AB = sh

Now, we are asked to compute Sin C - Cos C.

$Sin C = \frac{opp}{hyp}$

⇒ $Sin C = \frac{AB}{BC}$

$= \frac{sh}{h}$

= s

Sin C = s

$Cos C = \frac{adj}{hyp}$

$\implies Cos C = \frac{AC}{BC}$

⇒ Cos C = $\frac{rh}{h}$

Therefore, Cos C = r

So, Sin C - Cos C = s - r, which is OPTION C and is the right answer.

Novay_Z [31]

Answer:

Step-by-step explanation:

You could multiply all of equation A by 1/6 and all of equation b by -1/4 to get

A. x-3/2y=-1/3 and B. x+1/4y=/5/4, then subtract the equations from each other to solve
