The square mural in Olivia's classroom has dimensions x by x.
Then she paints a mural of dimensions: x+5 (the length) by x-2 (the width).
Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is
(x+5)(x-2).
<span>
each side of the classroom mural is 7 feet means that x = 7 ft,
</span>
thus the area of the hallway mural is :
(x+5)(x-2)=(7+5)(7-2)=12*5=60 (square feet)
Answer:
<span>C. (x + 5)(x – 2); 60 square feet</span>
Answer:
Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.

Step-by-step explanation:
Given
CB = 14in
B as midpoint
Required
Determine CD and BD
<em>Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:</em>
<em></em>

Reorder the first equation

Substitute 14 for CB
