the first floor of a house consists of a kitchen, playroom, and dining room. the areas of the kitchen, playroom, and dining room are in the ratio 4: 3: 2. the combined area of these three rooms is 189 square feet.

what is the area of the kitchen?

The area of the kitchen is 84 square feet

Step-by-step explanation:

Let

x-----> the area of the kitchen in square feet

y ---->  the area of the playroom in square feet

z ---->  the area of the dining room in square feet

we know that

----> equation A

so

----> ---> equation B

----> ---> equation C

substitute equation B and equation C in equation A

solve for x

therefore

The area of the kitchen is 84 square feet

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
