The answer is A
- you have to substitute 5 for x in both equations
- solve both equations separately
- subtract the functions
Hi,
Work:
Equation;

First add up numbers and distribute 9 over parenthesis.

Second: collect like terms.

Move variable 59p to left side and change its sign.

Then move constant 123 to right side and change its sign.

Calculate the difference.

Divide both sides of equation by 59.

Hope this helps.

Answer:
Your required answer is option is {20}.
Step-by-step explanation:
Hey, there!!
The reason for above answer is we generally find intersections among the sets by extracting the common elements of the sets.
Here,
R = {10,15,20}
S = {20,25}.
Now, 20 is common im both so,
R intersection S = {20}.

The formula for finding the area of a rug:

Plugging in the values we know, we can solve for s.

Take the square root of both sides.


is approximately equal to 8.89
So, 8.89 feet is the answer.
