<em><u>The equation can be used to find the actual length of Gregory's room is:</u></em>

<em><u>Solution:</u></em>
Given that,
The scale that he uses is:
1 cm : 4 feet
On this drawing, the room is 3 cm long
Let "x" be the actual length of room
Therefore,
1 cm : 4 feet
3 cm : "x" feet
This forms a proportion. Therefore,

Therefore, Option C is correct
Given that,
Rob chose A as the correct answer. Which is,

But option A is wrong
So, Rob made a mistake in measuring the equivalent ratio, it should be 
Answer:
y-x
Step-by-step explanation:
I assumed you meant that you wanted me to rewrite the expression without the absolute value signs. Since the absolute value of a number will be the same whichever way you place the numbers, you can rewrite |x-y| as y-x, as x is less than y.
Answer: 2in
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
The correct scale on the blueprint is : 1/4 inch represents 3 feet.
So, the proportion is: 1/4 inch/ 3 feet = (1/4) /3
For 24 feet:
x inches /24 feet = x/24
So:
(1/4)/3 = x/24
Solving for x (inches)
[(1/4)/3 ] (24) =x
x =2 inches

Answer:
(x-2) and (10x+7)
Step-by-step explanation:
10x²-13x-14
10x²-20x+7x-14
10x(x-2)+7(x-2)
(x-2)(10x+7)
the factors are (x-2)(10x+7)
meaning that the length and breadth are (x-2) and (10x+7)
