Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
Answer:
3.5x+6.7
Step-by-step explanation:
simplify step-by-step.
3.5x+4+2.7
Combine Like Terms:
=3.5x+4+2.7
=(3.5x)+(4+2.7)
=3.5x+6.7
Answer:
(x+6)^2 + y^2 = 1 then isolate y^2 by subtracting (x +6)^2 from both sides, we get
y^2 = 1 - (x + 6)^2
expanding the right side, we now have
y^2 = 1-(x^2 + 12x +36)
y^2 = 1-x^2-12x -36
y^2 = -x^2 -12x - 35 therefore the solution is choice A

Answer:
Slope of the line 
Step-by-step explanation:
Given that,
The point 
lies on the curve 
.
If 
is the point lies on 
.
To find:- Find the slope of line 
.
So,
The coordinates of point when it lies on
if 
then 
So, ≡ 
and many points can be calculated by given Equation.
Using the formula when two points 
.
Then, substituting the coordinates we get,
⇒ 
Therefore,
Slope of the line
