The perimeter of a rectangle is 15x + 17y
If the length is 7/2x + 7y then find the width of the rectangle.
Answer choices:
A. 4x + 3/2y
B. 8x + 3y
C. 8x + 10y
D. 4x + 3y

c

Step-by-step explanation:

8x+3y

Step-by-step explanation:

You will need to subtract double the length by the perimiter since there are 2 sides of length

15x + 17y - (7/2x + 7y)2 =?

(15x + 17y) - (14/2x + 14y)=?

(15x+17y) - (7x + 14y)

Normally we would follow BPEMDAS but because there are not like terms in the parenthesis this is not necessary

8x+3y

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
