Sandra bought 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each side of t
BARSIC [14]
Answer:
length of each side of the room is 2√30 which is approximately 10.9545 ft

Explanation:
The area of the square can be computed as follows:
Area = l²
where l is the length of the side

We are given that:
area = 120 ft²

Substitute with the area in the above equation and solve for l as follows:
area = l²
120 = l²
l = √120
l = 2√30 ft
This is approximately equal to 10.9545 ft

Hope this helps :)

Solve for B. <br> R = x(A + B)<br><br> A) B = (R - A)/x<br> B) B = (A - Rx)/x<br> C) B = (R - Ax)/x
Vera_Pavlovna [14]

R = x(A+B)

distribute

R=Ax+Bx

subtract Ax from each side

R-Ax=Bx

divideby x

(R-Ax)/x =B

A pair of equations is shown below: y = 8x − 9 y = 4x − 1 Part A: Explain how you will solve the pair of equations by substituti
insens350 [35]
Here's the first part:

y = 8x - 9  --(i)
y = 4x - 1 -- (ii)

then in eqn( i),
 4x - 1 = 8x -9   (from eqn( ii) )
 -1 +9 = 8x -4x
8 = 4x
x =2 

then in eqn (i),
y = 8*2 -9
   = 16 -9
   = 7

The 2nd part:

When these two equations are graphed, at point (2,7) the lines representing the two equations intersect because these values (2,7) satisfies the given equations.
