The length of a living room is 12 feet and its width is 1012 feet. The length of the room is being expanded by x feet. Choose an

Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

$A=LW$

we have

$L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft$

substitute

$A=(12)(10.5)=126\ ft^2$

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

we have

$L=(12+x)\ ft\\W=10.5\ ft$

The new area is

$A=10.5(12+x)\ ft^2$

The expanded form of the expression is

Apply distributive property

$A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2$

Sound intensity,l, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by

dybincka [34]

The vertical asymptote is r = 0. The intensity is undefined at the source. The horizontal asymptote is I = 0. As the distance from the source increases, the intensity goes to zero. The intensity decreases as the distance increases.

Which system of equations does this graph represent?

sveta [45]

Equation of the linear graph is given by: (y - (-7))/(x - (-3)) = (-2 - (-7))/(2 - (-3)) (y + 7)/(x + 3) = (-2 + 7)/(2 + 3) = 5/5 = 1
y + 7 = x + 3
y = x - 4

Also, for the parabola: -(3)^2 + 2 = -9 + 2 = -7
Therefore solution is:
y = -x^2 + 2
y = x - 4

Given: ΔXYZ AB is a midsegment parallel to XY. The slope of AB is 2 3 . What is the slope of XY?

Bezzdna [24]

The slope of XY is the same as the slope of AB because AB is parallel to XY and parallel lines have the same slope.
