X/y=z
if we know x and z
solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y
therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
=?
solve
first factor them
=?
x^2-x+1=?
the poly is x^2-x+1
if we know x and z
solve for y
x/y=z
times both sides by y
x=zy
divide both sides by z
x/z=y
therefor
(x^4– 3x2 + 4x – 3)/?=(x^2+x-3)
so
solve
first factor them
x^2-x+1=?
the poly is x^2-x+1
Answer:
The park is <u>31 inches</u> wide in the drawing.
Step-by-step explanation:
Given:
Vicky drew a scale drawing of a city. She used the scale 1 inch : 2 yards.
The actual width of a neighborhood park is 62 yards.
Now, to find the width of park in drawing.
Let the width of park in drawing be
The scale drawing of the city is 1 inch : 2 yards.
So, 1 inch is equivalent to 2 yards.
Thus, is equivalent to 62 yards.
Now, to get the width of park in drawing by using cross multiplication method:
By cross multiplying we get:
Dividing both sides by 2 we get:
Therefore, the park is 31 inches wide in the drawing.
